Hotspot Analysing in ArcGIS

geoprocessing environment settings are additional parameters that affect the tools results. current workspace tools that honor the current workspace environment setting use the workspace specified as the default location for geoprocessing tool inputs and outputs. scratch workspace tools that honor the scratch workspace environment setting used to specified location at the default workspace for output data sets. the scratch workspace is intended for output data you do not wish to maintain. the data are about cold hot spot. here, hot spot actually means that a small area or region with a relatively more calls in comparison to its surroundings. first we should check the data projections by if they are not in same projections, then project them in the same projection. for project you find the tool and data management tools projection and transformation and then project input: the input must be the unprojected shape file which we want to project. output: we should gave output name by which we recognize that is projected. output coordinate system: we can add coordinate system by importing the other shape files coordinate. we can Search the tools in search toolbox. it's very easy to use either reminding where is that tool we need to perform. we can copy the projected feature for keeping that for further use. we can work on the copy feature for copy. we can search as copy features where we can go through data management tools features and then copy features. input: now we want to copy it. output: the name of output. integrate features and feature layers by inserting vertices where line segments cross are where segment endpoints are too close to other segments. clusters vertices to guarantee a minimum separation between vertices points and line segments. integrate permanently changes the inputs integrate does not create new data but instead modifies the original input features. if experimenting with this tool it is recommended to make a backup copy of the inputs. collect events converts event data such as crime data combines coincident points. it creates a new output feature class containing all of the unique locations found in the input feature class. it then adds a field named account to hold the sum of all incidents at each unique location this tool will only combine features that have the exact same X&Y centroid coordinates. you may want to use the integrate tool to snap nearby features together prior to running the collect events tool. incremental spatial autocorrelation measures spatial autocorrelation for a series of distances and optionally creates a line graph of those distances and their corresponding z-scores. z-scores reflect the intensity of spatial clustering and statistically significant Peaks he scores indicate distances where spatial processes promoting clustering are most pronounced. these peak distances are often appropriate values to use for tools with a distance band or distance radius parameter. this tool can help you select an appropriate distance threshold or radius for tool set of these parameters such as hotspot analysis or point density. the incremental spatial autocorrelation tool measures spatial autocorrelation for a series of distance increments and reports for each distance increment. the associated neurons index expected index variants z-score and p-value. hotspot analysis Getis-Ord Gi given a set of weighted features identifies statistically significant hot spots and cold spots using the Getis-Ord Gi statistic. this tool identifies statistically significant spatial clusters of high values hot spots and low values cold spots. it creates a new output feature class with a V score p-value and confidence level bin Getis-Ord Gi for each feature in the input feature class. inverse distance weighted and interpolation determines cell values using a linearly weighted combination of a set of sample points. the weight is a function of inverse distance the surface being interpolated should be that on a locationally dependent variable.
