None None None ESRI ArcCatalog 9.3.1.1850 File Geodatabase Feature Class http://www.nps.gov/gis/data_info/ 2005: Sonya Pope collected and processed data to replace Sand Bench Trail arcs. Amber Napton and Jim Hancock collected and helped process data to replace the Grotto and Canyon Overlook Trail arcs. Accuracy was conducted by review of the trails and routes by Backcountry Division personnel, consistency with the Zion National Park Compendium dated November 15, 1993 and amended March 23, 2002; quality control of GIS personnel for name consistencies, spellings, and locations. This data is finalized but will be updated as opportunities arise to GPS additional trails and replace existing ones. Many of the trails have been GPSed by different employees of the park; when known, it is noted in the attributes (see "source") in the trails.aat table. Trails that have not been GPSed to National Park Service standards will need to be edited against newly acquired 1999 digital true color orthophotographs of Zion National Park. All GPS data was differentially corrected and exported from Trimble Pathfinder Office to ArcInfo coverages. This data is a combination of corrected GPS (global positioning system) data, heads-up digitizing, and table digitizing from 1:24000 USGS maps. When the source is known at 100% confidence, it is provided in the data set (attribute 'source'). This data will eventually be updated by comparison with 1999 orthorectified true color digital orthophotos. As new trails are GPSed, they are added to the coverage and the previous trails which have been replaced are deleted. Attribute information is updated accordingly. The GPS generated data process is as follows: The features were logged on a Trimble GPS using the Zion_trlrte or ZION_generic data dictionaries. The spatial data were downloaded from the GPS unit to a personal computer and post-processed for differential correction using base station files from the Dixie National Forest in Cedar City, Utah. The corrected files were exported to an AML. The process software and version was Trimble Pathfinder Office 3.0. The AML was run to create the coverage; the resulting coverage was checked for attribute completeness during an ArcEdit session. The process software and version was ESRI Arc/INFO 8.3 May 19, 2005: Coverage edited using ESRI Arc/Info 9.0; Chinle trail segment replaced through GPS using Trimble Pro-XR; one small segment edited using HUD with 1999 True Color Aerial photography to connect old segment with new Chinle segment. 20040820 Zion National Park, Resource Management & Research, GIS GIS Specialist GIS Specialist mailing and physical address

Data processing and digitizing by Dan Alberts (GIS Tech) and Amber Napton. ground condition New data for the Grotto and Canyon Overlook trails was created during the 2005 field season. The Cultural project that created this new data was the "Documentation and Condition Assessment of the Grotto and Canyon Overlook Trails". This new data was utilized to create the Cultural historic trails features linear coverage, histrln. This new data is mostly GPS data. In locations where GPS was not possible, Heads Up Digitizing (HUD) using true color aerials as a background and measurements from field observations were used to create the remaining arcs. In the Arc/Info ArcEdit environment, deleted the existing Grotto and Canyon Overlook Trail arcs. From a copy of histrln, unsplit the trail tread arcs based on the source of the arcs; GPS versus HUD. Moved these arcs into the trails coverage. In the Arc/Info Arc environment, built the coverage to reestablish topology. In the Arc/Info ArcEdit environment, created route subclass "trails" and created route features based on name. In the Arc/Info Tables environment, added attribute items to the Route Attribute Table (RAT) which are also in the Arc Attribute Table (AAT); Name, Horse_Use, Compendium, and Comment. Back in the Arc/Info ArcEdit environment, populated the new RAT attribute fields as needed.

The old arcs were deleted. Tolerances were set. ArcGIS 9.2 and ArcWorkstation 9.2 20080616 Wrangler Trail was GPS'd using Trimble ProXH; pdop had to be raised slightly in order to capture satellites. Data was exported using PFinder Office as a shape file, converted to coverage using arc2shape.aml; data was 'cleaned' because of duplicatearcs and arcs having to be 'flipped' so all were in the same direction. ArcWorkstation 9.2; ArcMap 9.2; PFinder Office 20080714 The majority of Lower Emerald Pools Trail was GPS'd using Trimble ProXH. The part closer to the pool wasn't GPS because of the rock over the pool. It was impossible to get satellite signals. The following trails were GPS'd using Trimble ProXH : Cable mountain Trail, Deertrap Mountain Trail, a part of the West Rim Trail (from Lava point to Scout Lookout), La Verkin Creek Trail and Kolob Arch Trail. The folllowing trails were GPS'd using Trimble ProXRS: East Mesa Trail, Angels Landing Trail, Kayenta Trail, Middle Emerald pools Trail, Upper emerald pools Trail, a part of the East Rim Trail (the part of the trail that goes from Weeping Rock to Observation point), a part of the West Rim Trail (from the Grotto to Angels Landing) and the majority of Weeping rock (the end of the trail wasn't GPS because it was impossible to get satellite signals). The PDOP had to be raised for some trails in order to capture satellites. Datas were differently corrected using Pathfinder Office. Datas were exported using Pathfinder Office as shape files. All the datas were corrected using Geometry repair in ArcCatalog and converted to coverages using shapetoarc.aml in Arc WorkSattion. Tolerances were set and coordonate systems described. Data were edited in Arcedit and cleaned using Nodeerrors and Intersecterr. All the trails were added in the coverage "Trails" using the arc command "put". Datas were edited in Arcedit and cleaned using Nodeerrors and Intersecterr. The topology was built using the arc command "build". The arc command "frequency"was used to check the name errors in trails.aat and trail.ratname.. Some names errors were corrected for the Emerald pools Trails. The command "frequency" was used to find check errors in trails.aat for : horse-use, compendium, projnm, surveyor, edit_by. Some errors corrected (lack of information or misspelled words). The arc arrows were checked in trails.aat, in order to creat routes by name in this coverage. The route and the section by the item "name" were deleted and an other were created for the coverage "Trails" with the arc command Arcroute. The length of the trails (in meters) were calculated using the arc command "Routestats". The item "Kilometers" was added in Trails.aat (length of the trails in kilometers). The items "Kilometers", "Miles" and "Feet" (length of the trails in miles and feet) were added in Trails.ratname. These length in miles, kilometers and feet were calculated in trails.aat and trails.ratname. Two items were added in the coverage Trails: - "Surface": describe the surface of a trail. It can be "Paved", "Not Paved" or "Bridge". The information about this item need to be completed. - "Condition": describe the condition of a trail. It can be "Good", "Bad", "Variable".... This item is based on the surveyor 's opinion and need to be completed. The majority of the trails is now GPS'd. The only parts not GPS'd are the part of the trails where it's very difficult to get satellites signals, and are very little part of the trail.
