Development of A Web-Based Solar Map

Project Type

Web-based GIS application

Client

The City of Charlottesville, Virginia

Streams Tech developed an ArcGIS-based web-application illustrating solar energy potential for all buildings in the City of Charlottesville, Virginia. Property owners can use this ArcGIS-based web app to determine the area of the roof suitable for installation of photovoltaic (PV) panels and evaluate the benefits. The tool calculates site-specific solar energy potential using extensive geospatial data, helps residents of Charlottesville reduce their energy bills and promotes renewable energy use in the region.

Key Features
Promotes the use of renewable energy
Informs property owners about potential costs and energy savings
Easy-to-use online app
A Web Based Monitoring Service for South African Water

Project Type

Web-based GIS application

Client

GeoTerraImage (Pty) Ltd

Streams Tech developed a web-based application for GeoTerraImage (Pty) Ltd. to help monitor the status of fresh water in South Africa. Fresh water is a critical and scarce resource, requiring an accurate monitoring system for sustainable water management. The website, called the South African Water, allows end-users access detailed, reliable, and updated information for better water resources management activities, such as compliance monitoring, water security, water license applications and water resource inventory. The system utilizes ‘big data’ capabilities on a cloud platform to regularly process the European Space Agency’s (ESA) Sentinel2 satellite imagery data, prepare water resources maps for the entire country and make the geospatial data available for download to the end-users. The system provides desktop-based access to reliable monthly data for all surface water bodies throughout South Africa, which is extremely cost efficient compared to field monitoring.

Key Features
A cutting-edge dashboard
Big data analysis using satellite image
Reliable and updated GIS data made available to end users
A Web Based Monitoring Service for South African Water

Development of Online Adopt-A-Hydrant Platform

Project Type

Web-based GIS application

Client

The Town of Purcellville, Virginia

The Town of Purcellville, Virginia initiated the Adopt-a-Hydrant program to allow citizens adopt local fire hydrants and commit to keeping them clear of snow. Maintaining the surroundings of fire-hydrants clear of snow helps emergency response crews easily find fire hydrants during snow storms. Streams Tech developed a map-based online platform for Purcellville’s Adopt-a-Hydrant program, permitting citizens to sign-up and adopt one or more hydrants and the Town staff to administer the program. It also allows the Town staff to send reminders for cleanup.

Key Features
Allow citizens view the hydrants available for adoption on a map
Allow citizens sign-up, adopt hydrants or make changes to selections
Town staff can view and manage the volunteers interested in fire hydrant adoptions
Development of GeoDASH — A Web Based GIS Application on Open Source Platform

Project Type

Web-based GIS application

Client

The World Bank Group

GeoDASH is a web-based Geographic Information System (GIS) application, which allows users to store, share and visualize spatial data. Its development was funded by the World Bank to help manage disaster risks under the Urban Resilience Project in Bangladesh. This software provides government agencies with a multi-stakeholder platform to collaborate, analyze data and prepare custom maps using data from distributed sources. Individual agencies can develop, maintain and own its GIS data and yet easily share with other agencies.

Key Features
A browser-based system for creating maps and analyzing GIS data
Data can be stored in a cloud or server, allowing remote access by users
Real-time data updates and administrator notifications
Capabilities to import/export GIS data files

Client

Japan International Cooperation Agency (JICA)

The Japan International Cooperation Agency (JICA) sponsored the development of the National Spatial Data Infrastructure (NSDI) platform to host geospatial data from different stakeholders using a secure server system and through an integrated web-GIS portal. The system provides the data owners full control of over their data, including who can access individual GIS data for viewing, creating maps and downloading.

Key Features
Users can create custom maps using multiple geospatial data from distributed sources
Administrator controlled user access, privilege and publishing of data
Integrated tools for mapping and analytics (e.g., routing and BBOX search)
Viewing of coordinates, elevation, address and reverse geocoding data
