ICA Commission on Open Source Geospatial Technologies names Spatial {Query} Lab ‘Lab of the Month’ for January 2017

I am very proud to announce that the Spatial {Query} Lab has been named ‘Lab of the Month’ in January 2017 by the International Cartographic Association Commission on Open Source Geospatial Technologies (ICA). This honor should certainly be shared by the fantastic students in the lab working on the open source-related curriculum as well as the community that uses the content and provides valuable feedback. Thank you all for your hard work. The ICA announcement can be viewed at: http://opensourcegeospatial.icaci.org/2017/01/geoforall-lab-of-the-month-texas-am-university-corpus-christi-usa/


Bird Eggs – Find of the Week

Today we are featuring an interesting list of bird eggs found in their nests. This list was found inside the back cover of a field book. Although the page doesn’t have a date on it, the entire field book was dated between April and June of 1908. Unfortunately, we found no explanation as to why the bird eggs were being counted. The list reads as follows: “Eggs of Small burrowing owl – seven in nest. Yellow headed woodpecker – five in nest. Bottlenest bird (oriole ?) – three in nest, perhaps not complete. Totache  – three in nest.” Totache is another name for… Read more »


More than Surveying – Find of the Week

This week we are featuring two field book pages that show schematic drawings rather than survey sketches. Although the Conrad Blucher Surveying Collection is primarily comprised of surveying and mapping related documents, we we have occasionally come across engineering related documents. This particular entry, from June 1938, was for Travelers Insurance Company and includes several detailed drawings of different parts of an oil line boom.


Drs. Smith and Rudowsky Present about {Map Scanning} to TAMUCC Presidents Council

Dr. Rick Smith, Director of the Spatial {Query} Lab and Dr. Catherine Rudowsky, Director of the Mary and Jeff Bell Library, presented about the {Map Scanning} project at the inaugural TAMUCC President’s Council Lunch and Learn on October 13th, 2016. We were happy to have the opportunity to present to the President’s Council about the status of the project and the local, state, and national impacts that the {Map Scanning} project will have going forward.

Land For Sale – Find of the Week

This week we are featuring an advertisement for “Large Beautiful Lots” for sale in Corpus Christi. The ad, from 1927, features a map showing the lots that were for sale. The lots ranged in price from $119 to $399 and could be paid off with $1 weekly payments! We  found it very interesting to see how much land you could buy in 1927 for less than $400.


Crosstown Expressway – Find of the Week

This week we are featuring a series of  six maps that show the right-of-way for a portion of  State Highway 286, known as the Crosstown Expressway, in Corpus Christi, Texas.  State Highway 286 has been designated on it’s current path from downtown Corpus Christi to Chapman Ranch since 1939. The six right-of -way maps shown below have a range of dates from October 1961 to May 1963. The final photo shows each of the six maps georeferenced to the ground locations of each map. Click on a map to expand it for a more detailed view. We found it very interesting to see… Read more »

113 Years of Shoreline Change – Find of the Week

This week we are featuring a unique map that shows the shoreline of two barrier islands changing over the span of 113 years, from 1848 to 1961. The map extent covers a small portion of Padre Island and Mustang Island and uses different types of lines to indicate the shoreline location for a specific year. The years featured on this map are 1848, 1855, 1902, 1937, 1941, 1945, and 1961. Although only seven specific years are indicated on this map, the range of time is what makes this a very impressive and valuable find.    


Blunders – Find of the Week

Even the best can make mistakes sometimes, but what is important is identifying and correcting any mistakes that have been made. In surveying, we have a special word for avoidable mistakes. A blunder is a mistake, big or small, that is often due to human error. However, with comprehensive procedures and diligent checks, blunders can be found and corrected. Examples of blunders include, but are not limited to: -Incorrectly reading an instrument -Copying down a number incorrectly -Tabulation errors -Instruments incorrectly calibrated

The field book page below is an interesting example of two blunders occurring at once. The first blunder occurred when a point… Read more »
