The USDA Geospatial Data Gateway is a great source for natural resources-related data and can be used to download pre-processed collarless topographic maps in MrSid format. This blog posting provides an alternative method for acquiring collarless topographic maps and helps to eliminate processing as stated in related blog postings.
Transform USGS Topographic maps from the GeoPDF format into a more GIS-friendly format - the GeoTIFF. GDAL, an open-source software program that has been specifically designed for use in reading and writing information to geospatial raster data formats. Find out how..
GeoTIFFs are a high-quality raster storage format that require large amounts of disk space. JPEG2000s provide the same high-quality raster appearance, but require significantly less disk space. This second in the series details how to create seamless basemaps from USGS Topographic GeoPDF's using this more efficient file storage format.
Learn to create seamless basemaps from the US Topographic maps in GeoPDF format by converting them into a "GIS-friendly" format such as GeoTIFF all with a basic script and Global Mapper 15.
This short blog will quickly walk you through downloaded the newest topographic maps for an areas of your choosing from the National Map Viewer. This free download platform provides users with access to free topographic data for the entire country.
This blog posting will build on the Obtaining Elevation Data from NOAA Digital Coast blog post and introduce you to working with LiDAR data within the LAS dataset environment. A LAS Dataset is one of the Esri storage methods for LiDAR data in the LAS file format. Here we will explore creating two of the most basic outputs, the Digital Elevation Model and the Hillshade Model.
Building on the last LiDAR blog post which covered an introduction to using mosaic datasets as a way to manipulate LiDAR data. Here we explore more in-depth processes that can result in useful and versatile products.
In past blog postings we have discussed how mosaic datasets can be a powerful tool when used with imagery data. This blog post will introduce how mosaic datasets can also be a powerful tool to quickly create highly useful and variable products from LiDAR data.
Building on skills and techniques learned from a previous blog posts: "Part 1: Create a Pansharpened Image Using ArcGIS", you are ready to take the next step! Stay tuned for the final blog posting of this series and put the pieces of the puzzle together to create a high-quality end product.
