To create this GIS layer, data was taken from the "2001
International Piping and Snowy Plover Winter Census:
Individual Census Reports" that were submitted to the US
FWS from individuals throughout the state. |
A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:250000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References sectionand the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our web pages at: http://www.geoplan.ufl.edu/education.html |

This data set was created using ArcView 3.2 The process steps for creating the snowy plover locations were as follows: 1. If a specific latitude and longitude was given for a snowy plover location in the "Individual Census Reports", that data was entered into a table in the format DD MM SS. If no coordinates were given for the specific location of the bird, then the coordinates of the survey site was entered into the table. If no coordinates were provided, they were determined from the accompanying field map and entered into the table. 2. Appropriate data from the "Individual Census Reports" was entered into the table as each record was created. 3. The latitude and longitude fields were converted to decimal degrees using the ArcView sample script "dms2dd.ave" 4. The shapefile was created by "Adding an Event Theme" using the decimal degree coordinates created in the previous step. 5. The shapefile was projected from the standard geographic projection to a custom FL Albers Equal-Area Conic projection using the ArcView Projector! extension. 6. Plover locations in the panhandle of Florida were checked against DOQQ's (from FL DEP, 1994, 1m resolution) and county boundaries (TIGER/Census data, 1990, 1:100K). Some points were moved to better line up with these data layers. Also, some points were moved to better match the field maps that accompanied the "Individual Census Reports". (Some coordinates reported were approximations and were not collected with a GPS unit.) 7. Plover locations outside of the panhandle and along the Gulf coast of Florida were checked against DRG's (USGS 1:100K) and a detailed coastline layer (from FMRI/NOAA, 1993, 1:40K). Some points were moved to better line up with these data layers. Also, some points were moved to better match the field maps that accompanied the "Individual Census Reports". (Some coordinates reported were approximations and were not collected with a GPS unit.) 8. The plover location along the Atlantic coast of Florida was checked against DRG's (USGS 1:100K) and county boundaries (TIGER/Census data, 1990, 1:100K). The point was moved to better line up with these data layers. Also, the point was moved to better match the field map that accompanied the "Individual Census Report," as the coordinates were not reported for this site. All data sets used to confirm accuracy were provided by FGDL (Florida Geographic Data Library) Version 3.0. 9. Once all points were checked for accuracy; the shapefile was projected back to the standard geographic projection using the Projector! extension. 10. The attribute table was modified to show the new latitude and longitude of the points. This was done by using the FieldCalculator request "[Shape].GetX" and "[Shape].GetY" for decimal degrees and using the ArcView sample script "dd2dms.ave" on these new fields to get the degrees, minutes, seconds values. 11. These correct values were then copied into the attribute table of the existing snowy_plover shapefile in the Albers projection. Process Date: 20010215 |
