Introduction

The Managing Elevation workflow provides a set of geoprocessing tools and best practices for managing multi-resolution elevation data using mosaic datasets, and creating additional datasets like slope or aspect that are based on that elevation data.

Check out the Try It Out tab to get a guided, hands-on walkthrough of the workflow tools, included setting them up and applying them to sample data.

Check out the Workflow tab for a deeper dive into the more technical best practices for managing elevation data using mosaic datasets.

What is elevation data?

Elevation rasters (digital terrain models or digital elevation models, for example) store elevation measurements for a given area in an evenly spaced grid. These datasets can also be used to derive datasets like hillshades, slope, or aspect to use for visualization or analysis.

Who uses the workflow?

The Managing Elevation workflow is typically used by people managing collections of elevation data with experience using mosaic datasets. Often, people using this workflow need to provide end users with derived products for visualization (like hillshades) or analysis (like viewshed calculations), rather than raw elevation data.

Requirements

This workflow requires specific technical experience and software, and is designed to work with certain types of imagery.

RequirementDescription

Suggested Experience

Software

  • ArcGIS Desktop (Standard or Advanced)
    • ArcMap 10.2+ or ArcGIS Pro 2.0+

Input data

  • Elevation rasters
    • Recommended: tiled TIFF, LZW compression, with internal tile size 128 or 256 pixels
    • Supported: TIFF, FLT, IMG, BAG, HRE, ASCII, LAS, and other common raster formats

Known limitations

There are no known limitations for this workflow.
