Visualizing Topobathy Digital Elevation Models (DEMs)

On April 18, 2016, Posted by , In ArcMap,NPS Workflow, By , With Comments Off on Visualizing Topobathy Digital Elevation Models (DEMs)

Creating eye-catching visualizations is crucial to a memorable presentation. Here we will introduce an Esri tool that allows users to “split” a topobathy digital elevation model (DEM) into two separate rasters, allowing for better visualization for submerged and topographic elevations. This blog will build on the “Developing a Topobathy DEM”…

Part 3: Create a Pansharpened Image Using ArcGIS

On September 10, 2015, Posted by , In ArcMap,NPS Workflow, By , With Comments Off on Part 3: Create a Pansharpened Image Using ArcGIS

Panchromatic sharpening, more commonly called pansharpening, is a process in which two raster datasets are fused together to create one high-resolution, easy to analyze raster dataset. This process utilizes one high-resolution panchromatic image and one lower-resolution multiband color image. By combining these two images, the final product not only has…

Part 2: Creating a Multispectral Mosaic Dataset

On September 10, 2015, Posted by , In ArcMap,NPS Workflow, With No Comments

Quickbird is a high-resolution commercially-owned (DigitalGlobe) “earth-orbiting” satellite that is used to collect high-accuracy imagery; this imagery is available in both panchromatic (black and white) and multispectral (a wide range of frequencies across the electromagnetic spectrum). While the data used in this example is unavailable for testing, some sample Quickbird…
