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.

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 »

Tarasco Language – Find of the Week

Today’s “Find of the Week” features a short list of words in the Tarasco Language. The Tarasco language (also known as Tarascan or Purépecha) is an American Indian language with origins in Mexico. This list was found at the front of the field book and contains three words. Each with a phonetic pronunciation and the meaning of the word. Although we looked through the whole of the field book, we were unable to find any further mention of the Tarasco language or why the surveyor made notes of these words. The field book is dated from late 1916 to early 1920 and… Read more »


Upcoming Features of BandoCat

We have been hard at work preparing to kick off three new initiatives in the {Map Scanning} project: Georectification of scanned maps Transcription of map indices Spatial search of scanned documents In order to get these initiatives off the ground, we needed to develop some new capabilities of BandoCat (BandoCat is our internally-developed map cataloging software). So, we have developed a new georectification tool, a new transcription tool, and a new spatial search tool. All three of these tools work within BandoCat and will soon be deployed to the S{Q}L staff so they can enrich the scanned documents with geospatial… Read more »
