Generally speaking, the information available falls into four major categories. These categories include culture, survey, pipeline, and well information layers. Each type of spatial information available is presented in layers that can easily be turned on or off. The layers included are: airports, cemeteries, city boundaries, government land boundaries, political land boundaries (which includes county, state, offshore, and gulf area boundaries), railroads, roads, ship channels, subdivisions, surveys (which includes blocks, abstracts, surveys, sections, lots, and tracts), water features, and offshore surveys. Some of the layers include annotation where available, such as abstract number for abstracts, and API number for wellbores.

Formats usually requiring purchased software

Autodesk DWG (Drawing) Format

Software Requirement: Generally, this file format is viewed using AutoCAD, AutoCAD LT, or one of the vertical products built on AutoCAD, like AutoCAD Map or AutoCAD Land Development Desktop. For more information about the different flavors of AutoCAD, please visit the Autodesk website. Our format of choice, that is available for immediate purchase and download, is AutoCAD R13. This makes it highly available to most of the copies of AutoCAD running currently.
Pros:
  • Gain a rich experience in working with map data
  • Plot your own information onto the map, like shot points, receiver points, and additional wells
  • Work with the elements in their spatial context. All elements contain location in either the State Plane, UTM, or Geodetic format
  • Run scripts to insert GPS information right onto the map (not included)
  • The entire county is contained in a single file
Cons:
  • AutoCAD may be too costly for some. (AutoCAD LT is much more affordable)
  • Users may not want to go through the learning curve required to work with AutoCAD
Purchasing: You can search and purchase Texas County Maps in the AutoCAD DWG format right on our website.

Autodesk DXF Format

Software Requirement: Normally this format is the choice of those who have other packages, like Petra, Canvas, Surfer, and any of a whole host of applications that can read AutoCAD R13 DXF files.
Pros:
  • Format can be read by many packages
  • Depending on the capabilities of the software, you may have a richer experience with the DXF format than with the free formats. (Some softwares do not allow manipulation of DXF. Please download a sample before purchasing)
  • The entire county is contained in a single file
Cons:
  • Purchasing software to work with DXF's may not be feasible
  • Some software packages allow importing of DXF's, but will not allow manipulation
Purchasing: You can search and purchase Texas County Maps in the AutoCAD DWG format right on our website.

Texas County Map Ordering Help FAQ

Source Date

Source Date is an indication of when the information was last updated. Some entries will include a date in the past, like 2005-05-02 (May 2, 2005), while others will indicate "UPDATED UPON ORDER". Files with a date in the past let you know that some formats will be available for immediate download upon successfully ordering the map, while all requests that indicate a Source Date of "UPDATED UPON ORDER" will require processing time (usually 1 business day, occasionally 2) before the files are uploaded and ready to download from your account. In the case of processing time, you will be notified when the file(s) are ready for download.

Datum

Datum types that are supported by our system are NAD27 and NAD83. NAD stands for "North American Datum". 27 and 83 refers to the years 1927 and 1983, respectively. Simply put, the datum ultimately refers to the parameters used to approximate the shape of the earth. With the advent of the GPS satellite constellation, it has been possible for us to get closer and closer approximations of the spheroid of the earth (as the earth is not a sphere, but a spheroid, which means that it is slightly oval). While a number of approximations have been used throughout the years, the two utilized by NAD27 and NAD83 are the most popular for mapping in the United States.

Which one should I use?

It depends upon your circumstances. Below are some factors that may play into your decision, if you are not sure.

NAD27
  • NAD27 is an older datum. (In truth, the spheroid parameters utilized by NAD27 is the CLARKE 1866 spheroid. With the GPS constellation, we have been able to get much closer to the approximation of the earth. That being said, it is quite amazing that Mr. Clarke got as close as he did, using the equipment of his day.)
  • NAD27 is still the most popular datum downloaded from our system, even though it is not the more accurate datum, due to the fact that many systems in place continue to use NAD27 extensively.
  • If you are confused, and don't know what to choose, NAD27 is a good default choice.
  • Conversions between NAD27 and NAD83 always introduce additional error, depending upon the method utilized. Some approaches are more accurate than others, but in the end, they all add additional error. It is best to choose the one that you predominatly work in the most to mitigate this issue.

NAD83
  • NAD83 is the way of things currently.
  • GPS uses GRS80, which is the ellipsoid utilized by NAD83 as well
  • Plotting GPS information may in some cases be easier and more direct with maps already in NAD83. (Many systems will make this seamless, however)
  • Wellspots (if included in the product you purchase) will be in the datum of the map. Many like to upload these locations into their GPS handhelds when doing recon work to locate wells. NAD83 may make this process less error prone.
  • Conversions between NAD27 and NAD83 always introduce additional error, depending upon the method utilized. Some approaches are more accurate than others, but in the end, they all add additional error. It is best to choose the one that you predominatly work in the most to mitigate this issue.

Projection

Due to the fact that the earth is not an actual sphere, (as well as the fact that the landscape is not uniform), it is absolutely impossible to determine a system that would give 100% precision when determining location, be it with Latitude and Longitude or any XY type of system. Therefore, any location is always based on projection of some kind.

Projections supported by our system are: Lat-Long, SPCS (State Plane Coordinate System), and UTM (Universal Transverse Mercator).

Zone

Zone is necessary when using a "flat-grid" projection system, like SPCS or UTM. (Zone has no meaning when using Lat/Long projection). Since flat-grid systems work in a localized area only, it is necessary to further determine which area that you are working in. For example, The Texas SPCS is divided into 5 zones, numbered from 4201 through 4205. The zones are oriented in wide bands from west to east. The UTM system, however, is oriented in north/south bands that go from the South Pole all the way to the north pole.

Units

The units that our system uses are: Decimal Degrees (used exclusively with Lat/Long projection), US Feet, and Meters. US Feet and Meters may be specified with any flat-grid projection (SPCS or UTM).

File Format

Our system supports the following file formats: DWG (AutoCAD Drawing), DXF (AutoCAD Drawing Exchange Format), DWF (AutoCAD Drawing for the Web Format), PDF (Adobe Portable Document Format), SHP (ArcInfo GIS Shape File), and E00 (ArcInfo Exchange Format).

For more specific information on what these file formats are, and what their optimal usage is, please visit the Texas County Map Requirements page.

Layers Included

Map files have multiple layers that may be included in the download. Currently, the Texas County Maps include these layers:

Texas County Map: Available Layers
Field Description
BASE The base layer includes airports, cemeteries, roads, rivers and water features, shorelines, railroads, and boundaries (city, county, state, and government lands)
TEXAS LAND GRID The Texas Land Grid layer includes blocks, sections, surveys, abstracts, and subdivision information.
PIPELINES The Pipelines layer includes pipelines, as well as embedded pipeline attribute information (only in selected file formats).
WELLSPOTS The wells layer includes the well symbols and API number (where available).

Pipeline Attributes

Indicates whether or not the map that you are interested in includes the pipeline attributes. Some formats do not allow embedded attribute information, or will not allow it to be utilized by the target application, while others will. Notably, DWG, DWF, SHP, and E00 formats work well with attribuates, while DXF and PDF do not.

For more information on pipeline attributes that may be included with the map, please see the Pipeline Attributes section of our site.

Well Information

Currenly, our system supports two levels of well information: Basic and Extended. Below is a description of what is included in each level:

Texas County Map: Available Layers
