no, raster images are typically edited in a destructive manner. when you make changes to a raster image, such as cropping, resizing, or applying filters, the original image data is permanently altered. however, some advanced image editing software allows you to work with adjustment layers or ...
Rasters representing thematic data can be derived from analyzing other data. A common analysis application is classifying a satellite image into land cover categories. Basically, this activity groups the values of multispectral data into classes (such as vegetation type) and assigns a categorical value...

What is Map Algebra (Raster Math)? Map algebrabasically involves doing math with maps. But the key difference is that it only applies to raster data. That’s why we also call itraster math. First, let’s review the different types of map algebra. Then, let’s practice with an example...
is displayed. The data format is also referred to as a raster or image format. The physics of what comprises the number in the array is a function of the geometry, the value of the pixel, and the color it represents and is related to its radiometry. It captures the interaction of ...
Location data is an incredibly useful resource when properly analyzed. The first step is to choose an interactive platform that offers maximum governance with the flexibility to use multiple sources, custom filters, and the ability to perform a diverse set of analyses. If you do your homework and...
Geospatial raster data is a complex set of information gathered from Landsat satellite enhanced Thematic Mapper (ETM+) sensors, which record light, infrared reflectance value, and their position in the grid. Location data such as color, height of a digital innovation model, and several variables ...
Raster data consists of grids or cells of pixels with spatial information associated with each cell, such as elevation, temperature or even land use. Raster data is used to create complex, high-resolution imagery, such as photographs and satellite images. For example, a satellite image represented...
A geospatial database is optimized for storing and querying data that represents objects defined in a geometric space, such as vector data and raster data. With data volume growing exponentially, a geospatial database provides the best manageability and security to analyze large, complex, heterogeneou...
What is location data? Also known as geographic information or geospatial data, location data refers to information related to objects or elements present in a geographic space or horizon. There are two basic types of location data: vector data and raster data. Vector: This form uses points, ...
