  • Developed GIS applications in C# using object oriented programming principles.
  • Developed GIS applications using ArcGIS products (ArcInfo and ArcSDE) to work with versioned database (Oracle spatial).
  • Developed applications to implement secured workflow for change management of rail network and rail assets owned by CSX.
  • Developed python scripts to reload EAM facilities data into Oracle database.
  • Multiuser Data Editing Environment. Worked with the client and developed tools to provide secured and simple means of editing base map feature classes. The Department of Statistics is responsible for maintaining base map. These tools, developed in .net, utilize versioning to allow multiple users simultaneously edit the database, in Oracle, and at the same time provide uninterrupted view of the existing database.
  • Successfully installed Postresql 8.4 and PosGIS 2.0 and explored the capabilities offered by open source products. Successfully created GIS database by importing shapefiles and Raster data. Explored the scope of accessing and working with PostGIS data with ArcGIS. Researched and experimented with Postgresql to improve the database performance and to analyze the essential capabilities like versioning and triggers required for multi-user GIS data editing environment.
  • GIS Application Distribution and Management System. This system provides developers with easy means of application deployment over the web and allows the developer to control over applications accessibility to the end users. For the end users, this system provides application updates and allows automatic application download, registration and unregistration processes. This system deals with both VB6 and .NET GIS applications and includes two developer end applications (built on .net framework), two user end applications (built on .net framework) and a XML document describing all applications deployed over the web.
  • Developer end applications include Add-ins in VB6 and VB.NET to export developed GIS applications and a macro in VB.NET to auto update application version and other attribute information.
  • End user applications include a standalone application which allows registering new applications and unregistering existing applications and a GIS application which provides with updated GIS application information. Web-based (GIS) Applications. Stand-alone/console applications were developed in .Net to provide updates on GIS/raster data. Both GIS (base map and other associated geodatabases) and raster data are periodically updated.
  • Such updated information/files are posted over the intranet to provide instantaneous updates. Some of the files that are updated constantly are raster files, base map and other roadway data.
  • Confidential is also responsible for providing roadway discrepancy reports to all district offices. A console application was developed to read the data from enterprise database and post the report over intranet dynamically given district number, month and year. This information could be accessed by other district employees and clients. Basemap Historic Data.
  • This web-based GIS application allows reviewing historic basemap data. This allows the user to see the changes of roadway data over a period of time. This application has been developed using ASP.Net, Dojo and ArcGIS Server 9.2.
  • Downloading Tiger Files. The purpose of this project is to provide an interface that will allow the user easy means of downloading various census data from census.gov. Some of the files that will be downloaded often are street files, tracts and blocks. Since 2008, Tiger files data files have proper naming convention which will allow downloading GIS data automatically with help of a stand-alone application.
  • A stand-alone application is being developed which exposes all available census data both at state and county levels.
  • The application automatically locates the file on the census website and downloads the data to the user’s local machine. It also adds essential data such as Florida state and county code values for the user convenience. Prepared a step-by-step procedure to include HTML help document with GIS applications with samples and updated previous applications.
  • This document provides guidance for GIS application developers at TRANSTAT in preparing and including HTML help documents to the GIS applications. This process will standardizes the way applications are being deployed and provides an easy access to help documents for all GIS applications. Layout Manager.
  • This application lets the user preserve, share and interact layouts by creating blob files. The user can simply export to, import from blob files to update or reuse layouts. These blob files can also be shared with other users.
  • This allows the user to save time by allowing the user to reuse/share existing layouts. Shield Manager. This application creates customized shields for routes of various functional classes (interstate/state/county/US/toll routes) and manages those application-generated shields by allowing the user to import/export the shields to an XML file and by offering some controls over the in-map shields to the user. These files act like annotation layers and could be used by any GIS user.
  • This application also includes many advanced functionalities such as smart labeling. Image Processing Tools.
  • These tools offer the user various clipping methods to create images. Image Review Application. Developed a GIS application to assist staff review statewide images before uploading into ArcSDE.
  • This time-saving application automates the review process while analyzing image quality. Spatial Reference Application.
