1.14 GLOBAL POSITIONING SYSTEM (GPS) REQUIREMENTS

GPS Receiver

To ensure that the appropriate type of GPS receiver is matched to the mapping application, an understanding of receiver capabilities and limitations is required. There are basically three classes of GPS receivers:

•Recreational Grade

These devices have an accuracy within five to twenty meters. These GPS receivers usually do not have the ability to "post-process" collected data, but usually have the ability to perform real time correction using Wide Area Augmentation System (WAAS). GPS receivers can be used to navigate to a specific area and/or compile uncorrected GPS data, using associated third party software to convert the collected data directly into GIS supported data formats. Most modern “smart phones/tablets”, auto GPS devices, and Garmin GPS devices fall into this category.

•Mapping Grade

These have an accuracy from sub-meter to five meters. These GPS receivers have the ability to log raw GPS data, enabling these GPS-collected data to be post-processed utilizing desktop GPS software and allowing locations to be refined or corrected to a higher level of precision than inherent in the raw data. This category of GPS receiver also has the ability to communicate with a base station, store attributes of features, use a data dictionary and upload data from the GPS device to a PC.

•Survey or High Accuracy Grade

These include instruments with associated software that can achieve one centimeter relative accuracy. These are used by land surveyors primarily for boundary, topographic, and geodetic surveys, photogrammetry, and other activities requiring high accuracy. Specialized training is needed to use this equipment.

The GPS receivers used to collect all GPS data for the VEGR will depend upon the project. However, regardless of the project, the GPS receivers must be of Mapping Grade or better. For certain engineering projects (buildings/bridges/surveys), Survey or High Accuracy Grade GPS devices will be required. The GPS devices must:

Routinely achieve 60 centimeter or better horizontal accuracy, using either real time or post processed differential corrections.

Operates in a 3D mode where the receiver requires signals from a minimum of four satellites to determine a 3D (latitude, longitude, and elevation) location (a fix).

Allow the storage of position fixes for features that are being mapped. When mapping point features, the receiver must be able to store position fixes (the minimum number depending on the quality of the receiver) for the feature. The receiver must have enough data storage capacity for a typical day’s worth of data collection.

Be user configurable for critical settings, including DOP, SNR, elevation mask, and logging rate.

Produce and store data in a format compatible with the base station data used to perform the differential corrections or have the capability to receive real-time corrections from the base station.

The Vandenberg GeoBase Office currently utilizes Trimble GeoExplorer 6000 series devices with Trimble Pathfinder Pro receivers and Terrasync GPS collection software. This setup routinely allows GPS technicians to achieve post processed 30 centimeter horizontal accuracy (Real Time accuracy is close to 60 centimters)

Field Data Collection Parameters

To achieve the target accuracy, all collected GPS data must be differentially corrected, either in real time or in a post process step. The following parameters will help to assure that accuracy standards are met:

Position Mode

All position fixes must be determined with 7 or more satellites

Elevation Mask

15 degrees above horizon.

PDOP Mask

Max PDOP = 3

Signal to Noise Ratio Mask (SNR)

If this parameter setting exists, set it to 39.0

Minimum Positions

If this parameter setting exists, set it to the manufacturer for point features recommendation that would, at a minimum, allow the GPS data collected to achieve the accuracy standard. Recommend using a minimum of 60 1-second positions. Solutions based on a single fix are not acceptable.

Logging Intervals

Intervals for point features will be 1 second. Line and polygon features should be collected as a set of point features that can connected using GIS software.

Logging of DOP

If the receiver allows, this parameter setting will be set to allow the logging of DOP data along with position fixes.

C. Attributing GPS Features

During GPS data collection, GPS technicians will collect and attribute GPS features based on the spatial feature in VEGR. For example, if a water line is being installed, attributes like pipe size, pipe composition, and pipe designation (Primary vs Secondary) would be required attribution. Please check with the Vandenberg GeoBase Office for questions on feature attributions.

D. Processing of GPS Field Data

All GPS data collected for the Port must undergo some post processing steps using GPS processing software before the data can be used to generate a GIS layer. The exception to this step is if the GPS device is able to achieve real time accuracy that meets the 60 centimeter accuracy standard. To assure accuracy standards are adhered to, the Vandenberg Geobase office routinely checks GPS locations of engineering, utility, and communications projects for accuracy.

The GPS processing software must be able to download GPS data files from the GPS receiver, and perform differential corrections. In addition, it must allow exporting the corrected data to a GIS compatible format (File Geodatabase or Shapefile), in the correct coordinate system. Refer to the section below for specific information on the required coordinate system.

E. GPS Base Stations for Post Processed Differential Corrections For post processed differential corrections, several resources exist for GPS base station data in California. The nearest operating base station with the highest integrity rating should be used. The Vandenberg GeoBase office has a base station located on top of building 11439 and runs 24/7. Base station files from this base station can acquired from the Vandenberg GeoBase office.

F. Output to GIS

As stated previously, the preferred GIS data submittals should be in either ESRI File Geodatabase or Shapefile formats. The GPS processing software must allow for exporting to one of these formats. CAD export files will not be accepted. Refer to the section below for specific information on the required coordinate system.

G. Elevation Data

If elevation data is required by the project, it will be referenced to the North American Vertical Datum of 1988 (NAVD 88) vertical geodetic datum. Elevations must be generated as orthometric heights (relative to mean sea level) determined using the GEOID99 (Continental US) geoid conversion model. Conversions from other geoid conversion models are not acceptable.

H. Spatial Reference

The all GPS data must be delivered using the VEGR Spatial Reference as noted below.

Projection: California State Plane

Zone:

California Zone 5, FIPS Zone 0405

Units:

I. Deliverables

If GPS data collection work is being performed by a contractor, final deliverables will include:

1.)

All GPS field data files, both uncorrected and corrected versions, must be submitted. If field data was collected in real time differential mode, then there will not be uncorrected files, and only the real time corrected files are necessary. If edits are made to corrected files (i.e., fixes deleted or offset), copies of both edited and unedited are to be submitted.

2.)

All GPS to GIS export files, using the correct spatial reference detailed in Section 2.4. GIS files must use either an ESRI File Geodatabase or Shapefile format.

3.)
