AVGPS
is a customized extension of ArcView-GIS software and provides a data transfer
bridge between a GPS receiver and ArcView 3.x. AVGPS allows access to point,
line and polygon GPS field data for automated collection, viewing, plotting
and integrated da ta analysis within ArcView.

AVSPRAY is a custom
extension designed to track spray aircraft using GPS and a PSION datalogger
which was developed for the Ontario Ministry of Natural Resources. Differentially
corrected GPS data is collected on aerial spray tracks over forested or
agricultural land, which is then processed using AVSPRAY to determine factors
such as spray coverage, spray overlap, spray coverage statistics, including
maps, tables, and charts. The system can be customized to meet theclient's
needs.

The ArcView
Utility Extension is a consolidation of a variety of sample Avenue scripts
that are provided by ESRI or ArcView users. Some of these scripts have
been altered by D.T. Enterprises in order to enhance the script or to correct
minor bugs. The Utility extension provides the following functionality:

|
QUIKTRAC is a web-enabled
positioning and messaging service designed to track and communicate with
single or multiple vehicles, assets, or persons in near-real time using
the ORBCOMM LEO (Low Earth Orbit) satellite positioning and messaging
system. All the client requires is an internet/web browser such as Netscape
or Internet Explorer and a Subscriber Communicator. All maps, position
reports and email messages can be accessed through the QUIKTRAC
server.
AVSPRAY Utilizes ArcView's AVENUE software development tool, ArcVIew MapCafe (Java Applet), and HTML Code. |

|
The ArcView
OBM Utility Extension provides an automated method of presenting selected
OBM ArcInfo coverages along with selected layers and feature types. A predefined
legend for each layer/feature type can also be selected. This allows a
user to quickly access pertinent information for selected areas (ie. MU's)
without having to add each coverage as a theme to a View (which is a tedious
and time consuming process).

As part of the delivery of an introductory course on remote sensing, course lectures were developed using HTML for ease of presentation and access by the students using the local university intranet/internet server. The course lectures were organized in the form of topics such as: the Electromagnetic Spectrum, Aerial Photography, Airphoto Interpretation, Landuse/Landcover, Geographic Information Systems, Image Processing, Satellite Mapping of Earth Resources, Satellite Mapping of Atmosphere and Water, Radar Imagery, Environmental Monitoring and Assessment. | |
|
This project consisted of a tracking and remote monitoring application utilizing low-earth orbit (LEO) satellite communications, the global positioning system, and a Web-based method of communications and display. Remote monitored locations (or vehicles) were linked using satellite communicators and GPS receivers through the ORBCOMM LEO satellite constellation which provided the wireless communications network. Messages in the form of monitored data, messages and positions were then passed to ground earth stations which transferred the data to the internet. At the receiving end, the client then received the information from a web-enabled GIS application server that was accessible using a standard browser. | |
|
Coordinated the design and development of a digital geoscience data compilation for the Wawa Resident Geologist's Office over a period of two years. This involved the use of desktop-GIS and consisted of acquiring /transferring /processing /digitizing various sources of information into a digital format; these data included various geoscience and geographic basemaps, and mineral resource databases. The result of the project was an integrated geoscience information system, the use of which required a small learning curve. A series of maps and a database were produced which were made available within the District for public use. | |
|
Coordinated the designed and development of a mineral resource/land use management system for the Ministry of Northern Development and Mines. This involved the compilation of natural resource and landuse data for the Wawa Resident Geologist's District. Databases were designed and data entered consisting of resource, land uses, environmental sensitivities, mineral deposits, geochemical samples, sand & gravel quarries, etc. All the digital data was entered into a desktop-GIS from which a series of maps with a report were produced displaying the of areas of high mineral potential, natural resource values and areas of environmental sensitivity. This data was acquired by Ontario Hydro for a study of the proposed -electric corridor from Manitoba. | |
|
Trial applications were completed using GPS/desktop-GIS applied to common functions in mineral resource sector. This included a GPS survey of a claim, location of mineral deposits, mine shafts &, tailings sites, trenches and pits on a mining property. In addition, several roads were surveyed using GPS followed by transfer of the data to desktop-GIS for comparison with 1:250,000 and 1:20,000 (digital and hardcopy) geographic basemaps. | |
|
Supervised and coordinated a pilot project using desktop-GIS to handle geoscience data compilations and analytical functions which had been primarily manual in nature for a major mining and mineral exploration company. The project involved: on-site training, data compilation, and technical support. The mining company used the results of this pilot project to guide future decisions in the acquisition of GIS technology for geoscience applications within the organization. | |
|
Completed a pilot project designed to determine the effectiveness of using GPS/GIS technology in operational field conditions during two spray programs. Herbicide and insecticide spray aircraft were passively tracked using GPS receivers. GPS positional information was differentially corrected, translated and presented using desktop mapping software. The project involved software development, hardware integration, field operations, data analysis and presentation. | |
|
Coordinated and implimented a project involving the development of a Windows version for a GPS/desktop mapping linkage software, including the addition of real-time GPS data acquisition and presentation for Windows-based, desktop mapping software. The project involved the integration of GPS, desktop mapping, and communications technology (radio modems). Field testing of up to four vehicles and a prototype automated vehicle tracking system was completed. | |
|
Coordinated the development and implementation of a project involving the use of GPS and desktop mapping software together with data telemetry using radio modems to map and track, in real-time, using the increased accuracy of Differential GPS. Accuracy and precision tests were completed using several DGPS techniques for comparison, including the United States Coast Guard, UHF radio modems, and post-processing. Range of operation and technical limitations for both real-time tracking and real-time DGPS were determined for each method and a final report was published as part of the Northern Ontario Development Agreement, Northern Forestry Program. | |
|
Two to five day short courses on the Global Positioning System (GPS), Desktop Mapping and Geographic Information Systems (GIS), and the integration of these two technologies, have been delivered to a variety of resource-related clients. The short courses involve preparing the short course manual, presentation media, development of a digital data set (basemaps and databases), software/data setup and course delivery. | |
|
Coordinated the development and implemented the use of portable GPS/desktop-GIS in a jointly sponsored project by Forestry Canada the Ontario Ministry of Natural Resources. The objective was to use ground and helicopter-borne GPS to provide a rapid, cost-effective way of mapping fire perimeters, identify and locate hot spots, provide decision support, and a quicker response time for a District Fire Office. | |
|
Completed several trial tests using portable GPS/desktop-GIS technology with the Sault Ste. Marie Search and Rescue Unit (SSAR). The trial tests were designed to demonstrate the effectiveness of GPS/desktop-GIS technology for search and rescue operations on land, air, and water. | |
