Mosaic dataset provides the most convenient means Here are some general guidelines to help you decide Mosaic, LAS dataset, or terrain datasetĪrcGIS offers three data types that can process point-based One key decision is the data type through which theĭEMs or DSMs will be made.
#CREATE DIGITAL TERRAIN MODEL ARCGIS PYTHON API HOW TO#
Once you know what you want to produce, you need to decide how to For analysis using the ArcGIS platform, consider using the Public, you might think about distributing in either TIFF or JPEGįormat. If the product is to be shared with the general For example, in theĬase of hydrology, watershed boundaries are a good candidate.ĪrcGIS supports many raster formats, so you have a choice of Then use divisions logical for the application. Weighted heavily for one type of application, such as hydrology, He or she needs for an individual project. An engineer can mosaic the different pieces Political boundaries, or an anticipated application? Since lidarĬollections tend to have multiple uses, splitting them up based onĪ regular grid system or political divisions like county boundaries Question is how? Will it be based on a regular grid system, If you have determined you need to split up your data, the next Going to go wrong (for example, power outage). The longer a process takes to execute, the more likely something's Sizes, it also keeps process duration on those datasets shorter. Not only does this keep individual datasets at reasonable Volume of lidar data, so consider splitting up the lidar processingĪs well. In this situation, you would want to make multiple rasters from this Points as one dataset, while possible, is likely to prove unwieldy. Off one dataset for analysis can be in conflict with practicalĬonstraints associated with dataset size. Potential sharing or distribution of the data. Intend to do with the raster in terms of analysis, display, and This process requires that you figure out how many rows and columns Will be producing one raster or a collection of rasters.
