Abstract:
Park boundaries in the State of Texas.



The statewide Texas boundary dataset is one component of the Texas Strategic Mapping Program (StratMap).  The StratMap program developed seven digital base map, or "Framework", layers for Texas.  StratMap is managed by the Texas Natural Resources Information System (TNRIS), a division of the Texas Water Development Board (TWDB).  All data produced through StratMap are available in the public domain.  



The StratMap boundary dataset produced files corresponding to multi-county councils of government across Texas as well as a statewide dataset.  Each boundary file has five themes including state, county, city, parks, and other (i.e. federal lands, landmarks, country clubs).  The data sources for each council of government coverage vary but could include digital orthophoto quads (DOQs), USGS digital raster graphics (DRGs), Texas Department of Transportation data, and local data from the council of governments or its component governments.  The attribute coding scheme is designed to accommodate several basic cartographic data categories such as feature type, feature name, jurisdiction entity, data source used in feature collection, data source date and revision date(s) if applicable.
Purpose:
To show boundaries of parks in Texas for the Texas Hazard Mitigation Package (THMP).



This data is suitable for general planning purposes.  Inconsistencies between data sources were not always resolved and in some cases features which should be co-existent will be represented by several contradictory lines.  This is most readily apparent where municipal and county boundaries should correspond but do not due to different sources of the input data.  Please see Process Step #1 for more information on how differences between data sources were handled.

StratMap does not warrant this data for any particular use and is not responsible for any damages resulting from the use of the data.  Users of these files should be aware that (1) StratMap data are not authoritative representations of legal boundaries, (2) StratMap boundary lines are subject to change and corrections, (3) StratMap boundaries were generated from the best available data which are subject to change, and (4) StratMap is updating boundary data and has a process for collecting and noting boundary changes.  Contact StratMap for more details.  Acknowledgement of the StratMap program and Titan Systems Corp.,is appreciated in products derived and used from these data.

Data_Quality_Information:
Logical_Consistency_Report:
Polygon and chain-node topology present.
Completeness_Report:
This data set includes polygonal representation of physical and political boundary data for the State of Texas.  The data has been subdivided and delivered based on each of the 24 Texas Councils of Government (COGs).

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The multiple boundary layers were visually inspected and compared to source maps by a second technician to ensure reasonable horizontal position accuracy.  Where necessary, areas were plotted at larger scales to aid visual inspection of detailed areas of the data set.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: Data photorevised to the DOQQs: +/-10 meters. Data revised to the DRGs: +/- 12 meters.

Process_Description:
This process step outlines the general data hierarchy used for producing boundary data for the Texas Strategic Mapping Program (StratMap).  Each dataset's position in the data hierarchy is determined by its spatial and temporal accuracy.  Spatial accuracy is the difference between a dataset's georeferenced location and the dataset's true location.  Temporal accuracy refers to how current the dataset is.

For county and state boundaries, only the DRG dataset was used.  For the municipal boundaries local data was used if supplied, otherwise the municipality was derived from the TxDOT DGN area files (temporally accurate) and revised to DRG files (spatially correct).  In this case only entire polygons were moved to a "best fit" of the DRG, individual vertices were not manipulated. Only non-contiguous polygons were moved in this manner.  County and state boundary polygons contiguous with other county and state polygons were left alone. 

For the parks and "other" boundaries the polygons were derived from TxDOT DGN area files when supplied and updated to the DOQQs.  In this case vertices were moved to fit the DOQQ.  If no TxDOT DGN area file was supplied the polygon was heads-up digitized from the DOQQ.  The TxDOT "County Maps of Texas: 1998" and corresponding map sheets were used to identify features to capture when not provided in digital format.

Process_Description:
Create park coverage.  Convert shapes from TxDOT DGN files levels 22, 24, 25, 32, 48, 53, and 54 into shapefile format.  These levels correspond to feature classes County Park, state park, national park, amusement park, forest, park, City Park, respectively. Revise boundaries to DOQQs.  Convert shapefile into ArcInfo regions coverage.
