Historically land surveying and geographic information systems (GIS) have been compared and contrasted. Many in the industry have argued that one provides more advantages or have discussed why one is better for the job at hand than the other. But the truth is these two topographical methods are not in competition; they are complementary tools.
GIS is an accurate method for systems integration and land surveying is a useful method for canvassing. GIS adds another layer of information to what surveying reveals. These days it is used frequently for natural resource management, developing simulations for things like seismic hazards, water retention, and soil erosion. It assists engineers working to design and build tunnels, sewer systems, and highways. GIS is used by professionals charged with locating potholes that need repair, and land that is available for development, estimating stormwater runoff, inventorying utility poles, managing utility networks, and creating subsurface 3D utility models.
This video will help you in developing GIS field survey application from scratch. We will be using PostgreSQL for storing spatial data, GeoServer for publishing WMS and WFS services and OpenLayers for providing WebGIS functionalities over the web. We will also use HTML, PHP, AJAX, JavaScript and CSS for development purposes.
