  • Collarless Topo Maps from USDA Geospatial Data Gateway

    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.

  • Downloading USGS Topo Maps from the National Map Viewer

    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.

  • HIFLD ArcGIS Online Open Data Site

    Historically, access to the Homeland Infrastructure Foundation-Level Data (HIFLD) has been restricted to applicants meeting a variety of criteria, such as working for a federal government agency, or state emergency management agency. With the release of their new ArcGIS Online Open Data website, the HIFLD has made data previously contained within the Homeland Security Infrastructure Program (HSIP) databases available, and open, to the public. 

  • Introducing the USGS Coastal Change Hazards Portal

    This new viewer from the USGS provides GIS and non-GIS users with important coastal change information for the entire United States. Here, users can search, view, share, save and downloaded a multitude of coastal change data.

  • Converting GeoPDFs with GDAL

    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..



  • Developing a Topobathy Digital Elevation Model (DEM)

    Topobathy LiDAR is the combination, or parallel collection of traditional terrestrial LiDAR and bathymetric LiDAR. Here we will walk through the process of creating a high-quality topobathy Digital Elevation Model utilizing a portion of the 2014 NOAA National Geodetic Survey (NGS) Topobathy LiDAR data.

  • LAS Datasets In ArcGIS 10.1

    A video introducing the fundamentals of working with LAS datasets and the LAS Dataset Toolbar.

  • Mosaic Datasets and LiDAR Data: Advanced Processing

    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.

  • Mosaic Datasets and LiDAR Data: An Introduction

    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.

  • RGB Shaded LAS Files of the Salt Pond Visitor Center

    RGB Shaded LiDAR LAS Files of the Salt Pond Visitor Center at Cape Cod National Seashore (Unshaded data Source MassGIS and USGS):

    See example here.

  • Using LAS Datasets to Create Functional Outputs

    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.

  • VDatum to Convert LAS Data into MHW Vertical Datum

    Bathymetric data is often in one vertical datum and terrestrial elevations in another. You open the data in ArcGIS and hope that the on-the-fly projection takes care of things, only to realize it only works for the horizontal datum. Learn the steps necessary to convert LAS data from NAVD 88 to MHW, these methods could also be used for other vertical datum transformations.   

  • 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.
