Description:
Abstract:
This data set contains one-foot topographic contours assembled from section-size ArcInfo coverages that were developed through a private-sector contractor using stereo plotting techniques and low altitude aerial photography. This data set is developed over a period of three years using aerial photography taken from 1980's through early 1990's, and it supports projects and functions at SJRWMD that could involve the use of detailed topographic information such as field-scale hydrological modelling, detailed environmental assessment, etc.
Purpose:
To support enginnering applications, hydrological modeling, environmental assessment, and many other projects that require detailed topographi information.
Supplemental_Information:
This data layer was digitized from the one-foot section-size contour mylar maps developed from stereo models based on low altitide aerial photographs. All of the approximately 1100 section-size coverages were compiled and digitized under contract #92W289 (SJRWMD). For more information, see the SJRWMD Water Resources Department, Division of Engineering, contact: Kristina Hickey.

Title: one-foot topographiy
Geospatial_Data_Presentation_Form: vector digital data
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No final accuracy check was made for this dataset. It defaults to the accuracy of the individual (TRS) sections.
Logical_Consistency_Report:
Individual (TRS) sections were quality-checked, but the assembled one has not been.
Completeness_Report: Coverage is sparse as the need for data by projects changes.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
No positional accuracy was checked and it is believed the positional accuracy is generally high because the linework matches well with the 1995 DOQ images and the line work was based on the low altitude aerial photography.

Process_Step:
Process_Description:
A. Scanned through /englib/covs/one_ft_topo/... directories and identified all those section-size coverages that satisfied the following conditions: 1. Contain polygon topology 2. Contain line topology 3. Coverage name did NOT contain utm There were 1008 sections that satisfied those conditions.

B. For each of all those 1008 section-size coverages, the tolerance values were set to: Fuzzy 0.001 Verified Dangle 0.001 Verified Tic Match 0.001 Edit 0.001 Verified Node Snap 0.001 Verified Weed 0.001 Verified Grain 0.001 Verified Snap 0.001 Verified Database ID 0 Transaction ID 0 before a clean and/or build.

C. The 1008 small coverages were mapjoined to four larger coverages due to the fact that there is a limit (max 400 coverages at a time) to mapjoin. In addition, an item EDGE was added all those sections that did not contain one, and this item was set to (-9) to distinguish it from 0 or 1.

D. The larger coverages were each projected from the existing "SP" to the UTM Zone 17 HPGN system (/gislib/amls/projection_files/sp27- utmhpgn.prj), then reset all the tolerance values to minimum or zero before a clean and build.

E. A final mapjoin was carried out from the larger and reprojected UTM coverages to create a master coverage sjr1ft.

F. Then the lines and polygons in the UTM coverage were inserted into SDE as separate layers of lines and polygons.
