chart junk : Unnecessary detail around maps and diagrams
Commands do not require interaction with the map, they just rely on surface. Tools on the other hand require interaction with the map canvas.
GIS hydrological models can provide a spatial element that other hydrological models lack, with the analysis of variables such as slope, aspect and watershed or catchment area.
Geo-coding is when you associate a place name or an address with map coordinates. Geo-referencing is the process of associating plain digital images taken from a satellite or a plane with map coordinates so that they can be overlaid on street maps.
GIS or spatial data mining is the application of data mining methods to spatial data. Data mining, which is the partially automated search for hidden patterns in large databases, offers great potential benefits for applied GISbased decision making. Typical applications including environmental monitoring. A characteristic of such applications is that spatial correlation between data measurements require the use of specialized algorithms for more efficient data analysis.
The District GIS software standards consist of the Environmental Systems Research Institute Inc. (ESRI) products and Google Inc. geospatial services and software. The ESRI standard includes the ArcGIS line of desktop and server software product lines. The Google standard includes the Google Earth Enterprise line of server side products and Google Maps for mashup type applications. Other geospatial software packages and vendors can be accommodated if necessary to meet specific business requirements.

Virtual Reality Modelling Language
Remote sensing refers to detection and classification of objects on or in earth without physical contact, generally attained through aerial sensors.
Remote sensing refers to detection and classification of objects on or in earth without physical contact, generally attained through aerial sensors.
Skills in spatial data handling, algorithms, data conversion, model building and database programming.
Land Information System (LIS) is typical to GIS, but related primarily to large scale and parcel-based system such as Automated Mapping and Facilities Management (AM/FM)
I am familiar with Arc Map, Arc catalog and Arc toolbox.
A GIS technician works closely with end users to identify GIS data requirements and handle technical issues. It is also the job of a GIS technician to manage data maintenance and manipulation and handle extraction activities along with ensuring preparation, planning and updating a variety of maps and drawings to be part of a GIS database.
A set of graphs and maps where items are linked in separate displays.
The two data structures that can hold spatial data include raster and vector.
Nature of data, government rules and policies regarding data retention and data privacy factors.
GIS tools on the other hand require interaction with the map canvas.
Spatial ETL tools provide the data processing functionality of traditional Extract, Trform, Load (ETL) software, but with a primary focus on the ability to manage spatial data. They provide GIS users with the ability to trlate data between different standards and proprietary formats, whilst geometrically trforming the data en route.
Competent decisions can only be rendered by reliable data and though GIS is an amazing data management tool, using it with GPS helps in validating the data analysis and results.
GIS is a system of computer software, hardware, data, procedures and personnel combined to help, manipulate, analyze, and present information that is tied to a geographic location.
Modern GIS technologies use digital information, for which various digitized data creation methods are used. The most common method of data creation is digitization, where a hard copy map or survey plan is trferred into a digital medium through the use of a CAD program, and georeferencing capabilities.
Well, it depends on the project really. Some of the default templates are really good and safe to use. I make the choice based on the project caliber.
Geostatistics is a branch of statistics that deals with field data, spatial data with a continuous index. It provides methods to model spatial correlation, and predict values at arbitrary locations (interpolation).
GIS - Adds the analytical capabilities (graphic+ attribute) while automated cartography and CAD lack (graphic only)
