What is an SDI ?



We can define an SDI (Spatial Data Infraestructure) as a computer network system composed by a group of resources (catalogues, servers, programs, data, applications, WebPages, and so on) that manage the Geographic Information such as maps, orthophotography, satellite images, toponims, etc. and they are available to download from Internet. This information supplies interoperability conditions (rules, specifications, protocols, interfaces, etc) that allow the user to download and use them, with only a web browser.

Data for Remote Sensing and GIS



One main feature for a person who is starting to study Remote Sensing and GIS sciences, is to know how to download the most useful data for his corresponding study area. Getting to know the scales and resolutions that better fixes to that area, downloading the necessary features... and so on, we will cover them in this post.

A workflow for " Collector "




Would you like to build an useful application in your mobile device using ArcGIS? Don't worry, it won't take long to discover the best features in one of the most  powerful GIS platform.

In this post, we are going to use an example with the Bike Stations of London, preparing a layer from a KML (creating a new symbology and saving it in a new style)  and upload it to ArcGIS Online and then, use it in Collector for ArcGIS.
