This map of the town of Rumney NH’s farm and forest resources was generated using Terrago Technologies’ Publisher for ArcGIS. The map was part of a comprehensive natural resource inventory completed for the town’s conservation commission. Attribute information can be accessed using the object data tool and data layers may be toggled on/off using the controls in the Layers panel. The Terrago plug-in is not required for viewing an basic geospatial capabilities.

This map of St. Martin was generated using Publisher for ArcGIS. Use the Map Layers controls to view imagery, land area, and man made structures.

The City of Byron, a small municipality in Georgia, needed to map and manage their water & sewer, but lacked the budget and expertise for a high-end GIS. Instead they obtained the relevant GIS data sets and used TerraGo software to create geo-registered PDFs with a linked GeoPDF mapbook that integrated forms and databases for managing their utility data. The GeoPDF provides geospatial information in a format that the city can freely distribute and easily use. For this sample file, use the Adobe Zoom tools to find the icon for the camera, which acts as a hyperlink to a still photo stored in the same GeoPDF file. Use the right-click context menu to gain access to the custom forms that are associated to a latitude and longitude (once submitted back to a database). Note that each of the linear features in this PDF has attributes associated to them. To view the attributes, use the Adobe Object Tool.

The anaglyph is used to provide a stereoscopic or 3-D effect to an otherwise 2-D display. This 3-D perspective, when put in the geospatial context, really allows the end user to better understand depth in the image. By adding depth to an image, the user can make better decisions based on the height of the geospatial feature in question. In this sample GeoPDF file, the anaglyphic display highlights the mountainous terrain of the surrounding area, which can help for site or route planning.

Every mapping application needs a good base map. This base map of the U.S. can be used in conjunction with TerraGo Technologies’ Composer suite of tools. A base map is especially handy for working with map books, as they need an index map to use as a starting point for the series.

This map shows geospatially accurate info and layers for the city waterlines. A mapbook using this functionality can be taken into the field for markup by city employees giving the techies back in the office spatially accurate edits to be rolled into the enterprise. 

Benefits include:

• Disconnected editing:  This PDF has all the waterlines fully attributed for reference in the field
• Compression:  This PDF has an ortho photo as a base layer which is a very large file. This file by itself would be 100’s of MB
• Easy to send:  This PDF contains 15 layers and an ortho photo.  If I wanted to send this map to someone with shapefiles, it would be 75 files plus a photo
• Specific Data:  Adding to the above, shapefiles would be for the entire city, if you only wanted a specific subset one could just print a geospatialPDF of the area of interest

GeoPDF from before and after Hurricane Katrina is a culmination of two multispectral satellite image products. TerraGo’s Publisher for Raster application generated the multispectral GeoPDF file and the Map Assembler compiled them in to a single file with views of several different acquisition dates.

Rapidly and efficiently mapping and detecting change over time is a critical capability for real estate evaluations, urban planning, disaster management, logistics planning, forestry, etc. TerraGo Technologies combines data sets of high-resolution, digital orthophotos acquired at different dates into PDFs that can then be used to quickly and automatically determine changes and alterations in terrain cover, land class and elevation.

The Google Earth revolution has allowed anyone to access satellite imagery directly from their desktop. But Google Earth data is limited to a true or natural color representation of the earth. False color or ‘color-infrared’ imagery represents the light that falls outside of the spectrum visible to the human eye and is often more useful. For example, vegetation in a false color image appears to be red and the healthier the vegetation, the brighter color red in the image. If the vegetation is not healthy due to environmental factors, the color will appear a darker shade of red or even brown. This provides the image interpreter with a quick visual assessment of the area of interest.

This GeoPDF was published directly from ArcGIS - with zoom in, data search, and easy distribution.  The USGS is using this to distribute 7.5 minute Topographic Quads

This image was acquired at 11:19 AM on 01/20/09 which was just minutes before President Obama’s inauguration. The GeoPDF was created from a JPEG snapshot of the landscape by georegistering the data using the TerraGo Composer Suite of tools.

Image interpretation has traditionally been a specialty task within most military organizations. GeoPDF bridges the gap between the image analyst producing the data and the decision-maker who relies on the data to make quick and effective decisions This particular GeoPDF has two different images embedded in it which allows the analyst to display change over a specific period of time. Each date is treated as a separate layer in the GeoPDF file and bookmarks are created to zoom the user to a specific location and scale in the image.

Traditionally, Landsat data have been limited to Remote Sensing scientists who have access to expensive and hard-to-use analysis software. With GeoPDF we are able to export all 7 bands from this multispectral image and dynamically assign a Red, Green or Blue color to each band interactively. We are also able to lock view state in the form of a Bookmark which means that the map composer is able to predefine specific band combinations. The default view state with this GeoPDF is with all of the Bookmarks exposed.
