Our GIS Catalog is stacked!


US Land Grid, Inc. (http://www.uslandgrid.com) has just made available for instant download our 2,700 GIS data product. Ready for instant download is the Texas and PLSS Land Grid, over 300 Tax Parcels, and countless counties of PDF maps. No more waiting for your different datasets, get one of the 2,700 GIS datasets or PDF maps that you need instantly and without any hassle.
Our land grid (http://www.uslandgrid.com/land.html) data has been ready for a few months now. Apart from offering multple datums at no charge, our data comes with the lots, the quarters and the surveys. We don’t separate layers that belong to the land grid, we give you everything. Without a doubt a largest live, ready to download, GIS dataset with over 1,100 products, our land grid data and texas survey data is the largest online GIS catalog for instant download.
Matching the vastness of land with tax parcels (sometimes referred to as surface parcels, parcels, or surface ownership) completes the picture between land allotment and land ownership. Tax parcels (http://www.uslandgrid.com/parcels.html) become the meat in the sandwich between the land grid and surface leases. With over 300 counties of tax parcels ready for download online, our tax parcel dataset is largely focused on oil and gas plays – and from that perspective is very complete.
A new introduction, US Land Grid PDF Maps (http://www.uslandgrid.com/pdfmaps.html) provide 42 inch x 42+ inch maps that are beautifully designed and perfect for printing on plotters. Large scale and high detail, these maps are perfect for those of us that don’t have or use mapping software, or if we just want to print a quick map that can be marked up for presentation purposes. Oklahoma PDF Land Grid Maps are now complete. Texas is under construction. Watch this space, as we complete other states.
Our oil and gas data data is taking some time. We are working towards proving another excellent dataset that is tied to an industry leading data model and povides the consistency and accuracy in data you expect from US Land Grid. We hope to have our oil and gas GIS data release in early 2013.
In total, this means we now have over 2,700 products ready for instant download now available at US Land Grid. This is a huge number! As we continue to grow we expect this number to reach 5,000+ product ready for immediately delivery to your mapping program or PDF viewer. As we grow are datasets and offerings, we will also be growing our formats and delivery methods. If there is a GIS dataset that you would like to see, please let us know and we will do our best to make it work for you and US Land Grid.
From a GIS and mapping perspective, we hope you enjoy the intant delivery and service that we provide at US Land Grid – your new online source for Oil and Gas Data! We never close, and we never disappoint! Our industry leading guarantee makes any customer happy every single time. Please stop by and say hello.

Understanding the Texas Land Survey System


Understanding where land grid comes from is important. Below are some definitions to help you understand Texas land grid data a little better.

Texas does not use the Public Land Survey System. Texas has its own survey based on original Spanish Land Grants. Land grants from the State of Texas to railroad companies were often patented in blocks and sections. Some of the land transferred from the public domain by the state of Texas was surveyed and patented in units of square miles. The Texas General Land Office officially considers these units sections.
County patent survey lines from Texas General Land Office maps were interpreted as accurately as possible. In Texas, the highest level of land subdivision is the boundary of the state itself. The next level of subdivision is the Texas Railroad Districts which cover the entire state. These Spanish grants were surveyed on the metes and bounds system of measurement and are of irregular size and shape. Tracts are identified within a block by a unique number. Blocks and their associated tracts are not rectangular surveys but irregular metes and bounds surveys. Blocks do not conform to county boundaries and may span several counties since many were surveyed before county boundaries were established. Blocks are given the name of the person or institution that first conducted the survey. Labors can be subdivided into lots. These surveys are not always rectangular. Leagues can exist without labors but labors cannot exist without a league. Unlike the Congressional survey system that assigns a new abstract number each time a tract of land is sold in Texas the abstract number is assigned in perpetuity. Most of the Public School Lands are Leagues.
The Spanish encouraged ownership of the land as ameans of exploiting natural and human resources for the benefit of spreading Catholicism through the mission system. The early land grants were to native Americans with the understanding that they maintain the land under cultivation and production. The fact that Texas had its own national government and owned the public domain within its territory makes it different from any other state in the Union. The metes and bounds survey system made things more difficult.
The Texas General Land Office Abstracts Index shows the chronology of lands granted in each county.
Surveying Texas has resulted in numerous overlaps and unrecognized surveys. The GLO began to approve or disapprove the work done by surveyors via correspondence and issue land certificates to individuals qualifying under various acts. These individuals could locate onany vacant land within the State.
Examples of property descriptions and parcel plats are available. The user may turn on or off any level as required in a topographic file when it is used as a reference file.
