• Exercise: https://www.arcgis.com/home/item.html?id=1372abc4fb0c4ff0a7c66e8d9c869038
• Data: https://www.arcgis.com/home/item.html?id=862c63f5a50e4a29bb237369a9854838

Questions

1. What is a "Raster" object, and why do geoprocessing operations and map algebra expressions using rasters often result in temporary outputs?
2. What are the differences between raster datasets and raster bands?
3. What is the difference between raster functions in ArcGIS Pro and their equivalent functions in arcpy.sa or arcpy.ia?

Challenge 1

Create a script that determines what areas meet the following conditions:

• Moderate slope — between 5 and 20 degrees
• Southerly aspect — between 150 and 270 degrees
• Forested — land cover types of 41, 42, or 43 Be sure to use the map algebra expressions of the arcpy.sa module.

Challenge 2

Write a script that copies all the rasters in a workspace to a new file geo-database. You can use the rasters in the Exercise09 folder as an example.

WARNGING

If you do Challenge 2, you may get an error:

---

AttributeError Traceback (most recent call last) c:\program files\arcgis\pro\Resources\ArcToolbox\toolboxes\Conversion Tools.tbx#RasterToGeodatabase_conversion.InitializeParameters.py in

AttributeError: 'ToolValidator' object has no attribute 'isLicensed'

---

AttributeError Traceback (most recent call last) c:\program files\arcgis\pro\Resources\ArcToolbox\toolboxes\Conversion Tools.tbx#RasterToGeodatabase_conversion.InitializeParameters.py in

AttributeError: 'ToolValidator' object has no attribute 'isLicensed'

If you get this error, check to see whether the tool worked anyway!
