RS Web-Survey

The WEB portal for the distribution of Laser Mapping Data in streaming mode

RS Web Survey is a web application developed by Siteco for the consultation, distribution, editing of the data surveyed with any Mobile Mapping System (Road-Scanner, RIEGL, Optech, Z&F, and so on) through the web, in streaming mode. Images and point clouds are stored in an organized and structured database and can be consulted and viewed in their mapping context through a WEBGIS portal.

Description

A smart user-friendly interface allows the data consultation, deployment and download, through the definition of user-profiles with different access privileges, according to needs.

The management console, developed in a .Net environment, allows the organization of the data and their publication on the Portal starting from point clouds (LAS or LAZ format files), trajectories or spherical images captured in a survey.

The key technical features of the application are the following:

•PHP and Javascript language, based on open-source technologies,

•Apache webserver,

•Cartographic component created with Openlayers Javascript libraries,

•Display of point clouds via Potree Javascript libraries, and WebGL,

•Display of spherical images using Photo Sphere Javascript libraries,

•PostGIS database,

•Geoserver for WMS publishing layers.
