Exercise 5: Feature Classes (ArcMap) In ArcGIS, a collection of geographic features with the same geometry type (such as point, line, or polygon), the same attributes, and the same spatial reference. Feature classes can be stored in geodatabases, shapefiles, coverages, or other data formats. Feature classes allow homogeneous features to be grouped into a single unit for data storage purposes. For example, highways, primary roads, and secondary roads can be grouped into a line feature class named "roads." In a geodatabase, feature classes can also store annotation and dimensions.

14
GIS Training Manual for Strengthening of DEOC National Disaster Risk Reduction Center (NDRC), Kathmandu
Change Coordinate System Steps: 1. 2.
3. 4.
5.
In the Contents pane, right-click a map, and click Properties to open the Map Properties dialog box. Click the Coordinate System tab. (The current coordinate system is shown in the title of the property page. You can click Details to see details about the coordinate system. You can filter the coordinate systems shown in the dialog box by performing a search on a string value. This filters the list of coordinate systems based on folder names, coordinate system names, or well-known IDs (WKID). When using the filter options to reduce the number of available coordinate systems, only the folders containing the matching coordinate systems will appear.) Either browse to the coordinate system you require in the list, or type part of the name of the coordinate system you are trying to locate in the Search box. To set the map's coordinate system to be the same as that of a particular layer on the map, expand the Layers folder and expand the coordinate system. When the coordinate system is expanded, you'll see the layers that reference it. This is a useful way to ensure all layers in your map are in the same coordinate system. To set the map's or scene's coordinate system to be the same as that of a layer that is not in the map, click Import, and browse to a data source that is defined with the coordinate system you want to use. Add the coordinate system to your Favorites list to make it available to all your projects.
How to Align a Non-Georeferenced Image to an Existing Geographic Layer or Georeferenced Image Steps: 1. 2.
In ArcMap, add the existing shape file or the geo-referenced image that you are going to reference the new image against. Activate the Georeferencing menu (View/ Toolbars - check mark "Georeferencing")
15
GIS Training Manual for Strengthening of DEOC National Disaster Risk Reduction Center (NDRC), Kathmandu
3.
Add the image layer which you want to georeference. Note that if it is a .jpg file, make sure you choose the entire image file (below left). If you double click on the .jpg and see the individual bands listed in the dialog box (below right), you have drilled down too far. Back up and add the .jpg file.
4.
Zoom in to the area of your shape file that corresponds to the area of the image - this is not necessary but extremely helpful. If you need to look at the image to see what area it covers, right click on the image in the table of contents and choose Zoom to Layer, then go back to your previous view of your shape file and adjust the view of your GIS layers so that it displays approximately the same area On the Georeferencing menu, make sure that your Layer specified is the image you want to georeference. From the Georeferencing menu, choose Fit to Display - the new image should fill the screen. You should see the overlapping layers, and you may want to make your shape file data layer transparent or make the features hollow, so that you can see both the un-georeferenced image and the georeferenced shape file.
5. 6.
16
GIS Training Manual for Strengthening of DEOC National Disaster Risk Reduction Center (NDRC), Kathmandu
7.
Zoom in to the area of a location (such as a street intersection) which you can easily distinguish in both the image and in one of the already geo-referenced shapefile themes. These will be the control points, or shared points between your image and your existing geographic data.
8. 9.
Click on the Add Control Point tool Click on the first 'common point' on the digital image you want to georeference, then click on the same point in the existing geographic layer. Do the same with as many other 'common points' you can find until you like the result. You need at least 4 points. This procedure is also called "rubbersheeting". Remember, you always click on the un-geoferenced image first, then on your geographic data layer.
10. You can use the zoom and pan tools during this process to zoom in to see your points more clearly – this will also help to make your control points more accurate, rather than trying to create them with the entire area in view. Note: If you accidentally click the layers in the wrong order or make a bad control point, do not hit “Undo” or you may lose the last layer added and all of your control points. Instead, open the View Link Table and remove the last control point created. 11. You should check your control points occasionally by choosing View Link Table icon on the Georeferencing toolbar. This will show you all the control points, and when you have more than three it will show you the RMS error. You can delete control points that have large errors and reenter them or enter other points which result in a lower error. 12. When you have the image aligned with an acceptable RMS error, you should record the RMS error for data quality reporting. 13. When you have completed the georeferencing process, you can create a permanently georeferenced image by choosing Rectify from the Georeferencing menu - you can accept the default cell size that ArcMap calculates or set your own. For scanned maps, you can leave the resampling type set to Nearest Neighbor. Specify a name and location for the new image. The result will be a .tif image and a .tfw world file, which tells ArcMap where in the world this image is now located. 14. With this georeferenced image, you can now digitize new features from the map.
Creating a New Shapefile and Digitizing Basics in ArcMap Steps: 1. 2.
To create a new shapefile, open ArcCatalog by clicking the ArcCatalog button in an open ArcMap project. Navigate the directory structure to the left of the widow and single-click the directory that you would like to create the new shapefile in. Right-click in the directory space and choose New > Shapefile…

7.
In the Create New Shapefile Dialog, choose a file name, the type of file (point, line or polygon), and choose a projection by clicking the edit… button. Choose the Select… button in the Spatial Reference Properties dialog to choose the desired projection from a list. Although ArcMap can “project on the fly” it is important to use the same projection for all map layers in a project in order to preserve accuracy. Click OK twice. The new shapefile may now be opened in an ArcMap project and used for on-screen digitizing. There are numerous options available in ArcMap in terms of on-screen digitizing. This guide will only introduce the very basics in order to facilitate use. In an open project, load a base layer (satellite image, topo map, dem…) and the newly created shapefile. Bring up the Editor toolbar by right-clicking anywhere on the top button bar of ArcMap and choosing Editor. Make sure the new shapefile is listed as the Target, and Create New Feature is listed as the Task. Click the Editor button, and choose Start Editing. This activates the bar, and the Pencil tool may be used to edit new features. For a polygon, single-click each node and double-click to close the polygon. For a line, single-click each node and double-click to finish. For a point, click once for each feature. Choose stop digitizing in the Editor button when complete.
As stated earlier, there are many options with regard to digitizing in ArcMap. For more information, consult the help files or software manuals, particularly to understand table editing (in order to enter attribute info for your digitized features), snapping features that share similar boundaries, and

streaming (a setting you can use to automatically create vertices with mouse movements, rather than having to click each time). Modifications to an existing layer can be made using the Modify Feature task, rather than Create New Feature. Using the Edit Tool individual vertices can be moved, added or deleted. Right-click the vertices with the edit tool to see all options available.
Import x, y Data Tables to ArcMap and Convert the Data to a Shapefile Steps: 1.
2. 3. 4. 5.
6. 7.
To ensure ArcMap reads the data in the file correctly, use Excel to format the columns containing the Longitude (X, or Easting) and Latitude (Y, or Northing) values as NUMBER, with a minimum of 8 decimal places.2. The graphic below shows the distribution of positive and negative values for longitude (X) and latitude (Y) coordinates worldwide.
Descriptions of the contents of each column are also required in the output file. Label columns ID, Longitude, Latitude, Description, etc. After formatting the file, select all the cells in populated rows and columns in the table and navigate to File > Print Area > Set Print Area, or Page Layout > Print Area > Set Print Area. Navigate to File > Save As, and select a supported format from the choices available in Excel. Click Yes if Excel warns that certain formatting is not supported in this file format. Exit Excel. Click No when Excel prompts to save the changes. Note: If the changes are saved, Excel converts the file to an .xls or .xlsx Workbook that can only be used in ArcMap at version 9.2 and newer versions. To add the data from the .dbf, .csv, .txt or .prn file to ArcMap, navigate to Tools > Add XY Data and select the file. In version 10.x, click the Add Data button. Right-click the table name and select Display XY Data. Warning: At version 10.x, ArcMap applies the coordinate system of the Data Frame to the XY Data. This coordinate system is likely to be wrong for the data. Click the Edit button to open the Spatial Reference Properties dialog box. Click the Select button to select a coordinate system for the data. Note: If a warning message regarding the missing Object-ID field is displayed, it is safe to ignore it and click OK.

As an example, GPS data is most often collected in units of decimal degrees or lat/long, which is a geographic coordinate system. Open this directory. Most frequently, GPS data is collected on the WGS 1984 datum, so open the World folder, and select WGS_1984.prj. If the data has been collected on a different datum, click the link titled "Geographic Coordinate Systems and Areas of Use" in the Related Information section below to find the appropriate datum. 8.
After defining the projection, click Add, Apply, and OK on the Spatial Reference Properties dialog box. Click OK on the Add XY Data dialog box. The points are drawn as an event theme in ArcMap. Verify that the Event theme aligns with the other data in ArcMap. 9. To convert the event theme to a shapefile or geodatabase feature class, right-click the file name and select Data > Export Data. The points can be exported to a geodatabase feature class or to a shapefile. 10. The data can also be re-projected to the coordinate system of the ArcMap data frame during this process. Go to View > Data Frame Properties > Coordinate System tab, and select the desired output projection for the output data. To project while exporting, right-click the Events theme, select Data > Export Data, and change the radio button to export to the "coordinate system of the data frame". The output data is in the selected output coordinate system. 11. To project the event layer to a projected coordinate system using the Project tool, follow the instructions below: a) In ArcMap, navigate to ArcCatalog > Toolboxes > System Toolboxes > Data Management Tools > Projections and Transformation > Project. b) In the Project tool dialog box, fill the required parameters. Input Dataset or Feature Class: The feature class, feature layer, or feature dataset to be projected. Input Coordinate System (optional): The coordinate system of the input feature class or dataset. Output Coordinate System: The coordinate system to which the input data is to be projected. Geographic Transformation (optional): To be used to convert data between two geographic coordinate systems or datums. c) Click OK. Note: If ArcMap warns of a "different geographic coordinate system than other data in the map", navigate to View > Data Frame Properties > Coordinate System tab, and click the Transformations button to verify that the correct datum transformation is being used for the area where the data is located. Note: For a list of geographic (datum) transformations and their areas of use, click the link "Select the correct geographic (datum) transformation when projecting between datums". Under the Related Information section of the article, download the list of transformations for the version of ArcGIS Desktop installed on the computer.

Converting Between Coordinate Formats Steps: Within the Projections and Transformations toolset is a tool called Convert Coordinate Notation (Data Management > Projections and Transformations). This tool will convert between the following coordinate formats: DD—Decimal degrees DDM —Decimal minutes DMS—Degrees-minutes-seconds GARS—Global Area Reference System GEOREF—World Geographic Reference System UTM —Universal Transverse Mercator USNG—United States National Grid MGRS—Military Grid Reference System To convert between coordinate formats using the Convert Coordinate Notation tool, follow these steps: 1. Open the tool and select the table or feature class that has the values for conversion. 2. Set an output location for the converted values to be saved. 3. Set the X/Y fields and the Input/output coordinates. 4. Optionally, set an ID as the output will not carry over existing attribute fields.
5.
Set up a table join so that the new format can be accessed in the original table.
6.
Be sure to check out the Convert Coordinate Notation tool help for more information and also to learn the format of each notation.

Exercise 9: GPS and GIS An Easy Way to Add GPS Data to ArcMap Steps: 1.
The first step is to export your data to a GPX file using your GPS device (a format just about all of them support). Next, we’ll add the GPX file to Explorer by choosing Add, then GPS Data Files, as shown below:
2.
Then choose what you want to add:
3.
After making choices and clicking Add, we now have our GPX file displayed in ArcGIS Explorer Desktop with all the correct symbols.
22
GIS Training Manual for Strengthening of DEOC National Disaster Risk Reduction Center (NDRC), Kathmandu
4.
Next, right-click the layer in contents and choose Share.
5.
You can choose to share as either a layer package, KML, or Explorer map content file. We chose layer package since not only does ArcMap support LPKs, but the layer package also captures the symbols for display in ArcMap.
6.
Start ArcMap, then drag and drop the layer package onto your map. Below we’ve also connected to the ArcGIS Online world imagery basemap which serves as our foundation for displaying the nowconverted GPX file, just like we used in Explorer. Note that the symbols are exactly the same.

Browse to the KML file you saved and run the tool.
4.
Important: Do not rename output location from Users\….\Documents\ArcGIS.That prevented tool from running correctly. When creating file name for new .lyr file, do not leave spaces and use _UNDERSCORE _ instead of dashes. ArcMap might not crush because of that, but such file names might give you problem in your GIS analysis in a long run. If the process runs without error you will see a new layer added to your ArcMap project
5.
To save the new layer file as a shapefile, right click on the geo-information type (points, lines, polygons have to be saved in separate shapefiles) you want to save and select Data/Export Data…

Converting ArcGIS Layers to Google Earth (KML) Converting ArcGIS layers to Google Earth allows others to easily see layers without specialized software. Both ArcGIS and Google Earth Pro contain tools that allow conversion to and saving in KML format. Note: Be certain you are not allowed to share layers if they were not created by you
. Conversion using ArcGIS First, open the layer that you wish to covert. In the ArcToolbox window, expand “Conversion Tools,” then “To KML,” and select “Layer to KML.” When the “Layer to KML” window appears, first select the shapefile or layer for the “Layer” box. Next select a directory for the file to be created and provide a name for the file. Finally, you must enter a number for the “Layer Output Scale.” If your layer has a scale-dependent renderer, this setting allows you to export the KML at a specific level of resolution. Otherwise, it has no effect, whatever the number.
