How is raw OSM data processed for openstreetmap.org
Hiking & ActivitiesHow does OpenStreetMap get its data? OpenStreetMap (OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. What database does OpenStreetMap use? PostgreSQL database OpenStreetMap data is often stored
Calculate Bounding Box from Center at scale
Hiking & ActivitiesHow do you calculate bounding box? To make coordinates normalized, we take pixel values of x and y, which marks the center of the bounding box on the x- and y-axis. Then we divide the value of x by the width of the image and value of y by the height of the image. width
Find a geographic concentration of values?
Hiking & ActivitiesHow is geographic concentration measured? The simplest method to quantify geographic concentration is computing the share of exposure (EAD) held by the k largest geographies or regions in the portfolio relative to total exposure. What is geographic concentration? Geographic concentration indicates the extent to which a small number of regions account for a large proportion
Bbox for a particular feature of a layer in geoserver
Hiking & ActivitiesWhat is Bbox in Geoserver? The bounding box determines the extent of the data within a layer. Native Bounding Box—The bounds of the data specified in the Native SRS. These bounds can be generated by clicking the Compute from data button or they can be generated from the SRS definition by clicking the Compute from
How can I both resample and aggregate a raster using Terra?
Hiking & ActivitiesWhat is the difference between resample and aggregate? Whereas resampling is used for changing the resolution of a dimension, aggregating reduces the number of dimensions in the data. Examples of summary statistics include the mean, maximum value, minimum value or values of specific quantiles of the dataset. What will happen when resampling of a raster
Seeking highly customizable GIS platform?
Hiking & ActivitiesWhat are the two types of GIS software? There are two basic categories of GIS software: commercial and open-source. Commercial GIS software involves a paid license of some kind, either through subscription or a one-time perpetual license. Open-source GIS software is free for anyone to use. What is the latest version of GIS software? The
