What do we want? Field note descriptions! When do we want it? SOON! I can only speak on behalf of construction projects, but I’m sure all surveyors have had that client that just seemed to think that as soon as you start breaking down the tripod the job was done. Forget that you still have hours of drafting, double checking, and package preparation to conduct before you can hand off the finalized project. This impression that the field crew is the extent of our profession is likely the culprit of this stigma. Deadlines and demands for deliverables is always a… Read more »
Maps. Chances are if you’re on this site, you have some form of love for maps. Maps are these beautiful spatial interpretations that connect peoples and cultures alike. Whether it’s a geopolitical conversion of countries into perceived animals or a pocket map often found in the real-estate classifieds, maps have connected us one way or another. French & Haberer was a civil engineering firm in the Nueces County area in the early 1900’s that produced many of the maps and plats used by real-estate companies to advertise the beautiful cities and towns of South Texas. The French & Haberer Handy Pocket… Read more »
No matter what your profession is, every now and again we all just need a break. Back in 1924 surveyors weren’t able to escape reality by checking their Facebook notifications or calling friends or family on their cellphones. Instead, they created game boards on the backs of their preliminary plats! This simple pleasure serves as both a reminder of simpler times and a continued connection to humans across the ages. My only question to Mr. Blucher would be; what’d the client say when you turned in a plat with a chess board painted on the back?
Infrastructure and urban planning are often hot-topics in Corpus Christi. Any survey of the local population could tell you which streets have been in disrepair for decades and which ones seem to get torn up for reconstruction right after they’ve been reconstructed. We’re talking about you McArdle. Back in 1942 when Conrad M. Blucher was asked to conduct a survey across Nueces Bay for the proposed Sinclair Prairie Refining Company pipeline, he had the foresight to include plans for a channel that would be needed in the future when the local oil refineries increased production. This kind of future planning… Read more »
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 »
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.
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.
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 »
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.
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 »
