MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database.It is a file format (filename extension.sid) developed and patented [2] [3] by LizardTech (in October 2018 absorbed into Extensis) [4] for encoding of georeferenced raster graphics, such as orthophotos.
Shapefile – open, hybrid vector data format using SHP, SHX and DBF files (by ESRI) Spatial Data File – high-performance geodatabase format, native to MapGuide (by Autodesk ) TIGER – Topologically Integrated Geographic Encoding and Referencing
Government ArcGIS server addresses: Curated list of 3,500+ ArcGIS server addresses from federal to local. Updated once per week. Bad links fixed or flagged. NOAA Big Data Project: NOAA generates tens of terabytes of data a day from satellites, radars, ships, weather models, and other sources. While these data are publicly available, it is ...
The shapefile format is a geospatial vector data format for geographic information system (GIS) software. It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products . [ 1 ]
Digital elevation model, map (image), and vector data. Like any digital image, raster GIS data is based on a regular tessellation of space into a rectangular grid of rows and columns of cells (also known as pixels), with each cell having a measured value stored.
ArcGIS 9 was released in May 2004, which included ArcGIS Server and ArcGIS Engine for developers. [39] The ArcGIS 9 release includes a geoprocessing environment that allows execution of traditional GIS processing tools (such as clipping, overlay, and spatial analysis) interactively or from any scripting language that supports COM standards.
In a manner similar to that shown in figure 11, the stack-unit's occurrence (the map unit's outcrop), geometry (the map unit's boundaries), and descriptors (the physical properties of the geologic units included in the stack-unit) are managed as they are for a typical 2-D geologic map. [31] Raster-based stacked surfaces depict the surface of ...
Scanning a map results in raster data that could be further processed to produce vector data. When data is captured, the user should consider if the data should be captured with either a relative accuracy or absolute accuracy, since this could not only influence how information will be interpreted but also the cost of data capture.
