Mission
Applicability
IN ORDER TO ENHANCE DATA UNDERSTANDING
Provide unlimited & intuitive access
to historic aerials
Researchers
Texas Citizens
World Users
Create preeminent collection of Brazos County aerial images
~5,000 frames from Texas A&M & TNRIS
1930s to 2010s
Coverage of Brazos County, Texas
R&D
expert consultation
georeferencing methods*
web mapping services*
* Internal research grant
Print outs available at the Map & GIS Library (MGL)
Need of a magnifier
User needs to locate frame # and generate a list
MGL staff needs to copy/paste/deliver data
Lessons Learned
Future considerations
Data one-click away
Promote use of data by simplification
Objective: Find out which common software is the most suitable for georeferencing historical aerial image collections.
Software: ArcGIS (10.x), ENVI (4.8), and ERDAS (9.2).
Criteria: Performance & cost.

Software Test*
* Subjective to staff member (GIS student worker) skills and preference

Efficient work flows
3 tool bars are easy to use
ArcGIS enables mouse wheel VS. mouse click
ArcGIS and ERDAS-image layer menu
ENVI-multiple windows/image
ERDAS and ENVI provide multiple resolution windows/image


Interface

Results from all software can maintain an average Root Mean Square Error (RMSE) below 15
For processing time, ArcGIS is the most efficient (subjective)
Flaw of ENVI: Black frame (need extra work to remove)

Georeference
Performance
Performance assessment:
ArcGIS >= ERDAS > ENVI -> ENVI is eliminated

Edge
Edge Matching
Expected long mosaicking process- need to pursue effective edge matching
ERDAS-automatically match neighboring images
ArcGIS-auto geoferencing to match edges

Edge Matching Comparison
SIMILAR

ArcGIS Output
ERDAS Output
Summary
Conclusion:
ArcGIS is recommended

Interface Assessment:
ArcGIS= ERDAS > ENVI
Goals:
Explore
various platforms
for hosting aerial images
Seamless
web-based platform for visualization
Delivery of aerials over different
time periods

Intuitive
and
reliable
interface for both GIS & non-GIS users

Web Portal
Search by location
Display images
Download images
Accessible
Platform Requirements
Recommendations
AOI selection by
current view
or
selection box
Cart or basket for multiple dowloads
Provide context with current basemap for image referencing
Compression options for large or multiple imagery
Open Source vs Proprietary

The Gratifying Role of a GIS Educator at a Spatial University
Mapping Social Justice: Using GIS to Support Decision-Making in the U.S.-Mexico Borderlands
Highlight opportunities and challenges
Meeting with high school students
Dr. Edelmiro Escamilla & Miriam Olivares
Dr. Escamilla is studying perceptions of:
Construction Science as a college option
Construction Management as a profession
Illustrate distribution of income, big dollars in contracts and enrollment
Use GIS platform to promote an easier dialogue

Dialogo on the Border
Maps can be powerful to emphasize pressing challenges
Citizens, decision-makers and scientists can establish a dialogue
Maps simpler to decipher VS. lengthy documents

Predictions & Navigation Plan
Verification
Lessons Learned
Collaboration between NGOs, scientists and fishermen may fill government-function gaps
Local knowledge invaluable for prediction/verification program
Bathymetry + anecdotal information
Juxtaposition of fishermen knowledge + geomorphology based on scientific instruments - stronger predictions
GIS bridges all parts to generate a bigger outcome
A Fishermen Case Study: Predicting Reef Fish Spawning Aggregations
Fish spawning aggregations are shoals where fishes gather with the purpose to procreate
The conservation of reef fish spawning aggregations (FSAs) contributes to
sustainable marine ecosystems
and a
healthier economy
of the coastal communities.
Marine ecologists and conservation scientists have been working for decades on
characterizing
spawning aggregation sites for groupers and snappers, both commercially valuable and largely overfished, in the Meso-American Barrier Reef System (MBRS).

Texas Plains Climate Change (TPCC) interactive GIS web application: A layman interface to review predicted climate change
Why climate prediction is important?
Droughts and declining rainfall in the last decade
Dependency on aquifers and & water pumping restrictions
Predicted climate scenario clearly challenging to farmers --> Shift to less-water-demanding crops or give up farming
Dr. Modala studied effect of irrigation reductions in TP. Additionally, he bias-corrected climate models (2041-2070) using historic data (1971-2000)

Brazos County Registered Sex Offender Map Service
Challenge (2004)
The Geospatial Approach
Gather the data
Found ~30% risk classification data was not available
Regular updates were not scheduled
55% registered sex offenders were living out of compliance within the child safety zone
We created the 1st pilot web-mapping service

Outcome
Brazos County’s Parole Office established a 2-week database update plan
100% risk data have been recorded
RSOs population database grew from ~140 to ~260 - more accurate counts
Easier to understand mobility of RSOs population
Informed citizens
It provides a spatial reference - users understand dynamics at
neighborhood
gas station, corner store
night life, etc

The web-mapping service
Students looking for a real-world project
Free labor
City of Bryan needing to gather data on registered sex offenders
No budget for project
DPS data incomplete - relies on County reports

3 km x 1 km (1.15 sq mi) may take 7 hours for mapping with transects 30 – 50 m apart.
(ideal 10-100 m between transects)

By the way, did I mention this R&D project was necessary because Esri stopped developing the platform we were using (ArcGIS Viewer for Flex)??
