CLIDATA GIS for ArcGIS

Introduction

CLIDATA GIS for ArcGIS 10 (ClidataGIS10) is special extension for GIS program ArcGIS 10. This extension allow to connect GIS program to climatological database (CLIDATA), creating GIS layers from data store in database, text files (CSV), interpolate point (station’s) data into surface, calculate area statistics and so on.

Analysis

This submenu is used for statial analysis like spatial interpolations or area statistics on interpolated layer.

Interpolation

mainMenu

This function is used for spatial interpolation from point layer (station’s meteorological data) into surface (grid). User can select one of predefined interpolation methods IDW, LLR, Clidata Dem) for more detail see document “Interpolation methods in ClidataGIS”

Where:

  • Layer name of point layer which will be used as source for interpolation
  • Id Field name of field where are store station’s identifications (gh_id, eg_gh_id etc)
  • Value Field name of field, where are store values for interpolation
  • Number of points of stations in surrounding used for interpolation. Default value is 10 stations in surrounding
  • Max. distance maximum distance for searching stations
  • Method interpolation method used for interpolation. There are these methods defined:
     * IDW:    Inverse distance weighted 
 * LLR:    Local linear regression (elevation)
 * Clidata DEM:    Modified local linear regression
  • Modify grid possibility for change min, max value of calculate raster layer
  • Min interpolate values lower than min will change to min value
  • Max interpolate values higher than max will change to max value
  • Mask interpolate raster layer will masked by mask raster file c:\ClidataGIS\AG\CLIDATA\DEM\mask.asc

Area Statistics

AreaStatistic1

This function is used in case you want calculate average, minimal and maximal values in a given region (polygon) layer. Example: I want to calculate average altitude in my country border layer

Where:

  • Raster name of raster layer which will be used as source for calculation
  • Layer name of polygon layer used like Areas
  • Group Field name of field, which will be used for grouping (field Name in result table)
  • Calculate will calculate area statistics (mean,min,max) values in area defined in polygon layer from surface defined in Raster
  • Result will display calculated result in new table AreaStatistic2

Grid Calculator

Tool is used for do math operation between two raster layer gridCalculator1

Or

Do math operation with one raster layer and some constant

gridCalculator2

Isolines

Tool is used for make isolines from selected raster layer. User have to select from which raster layer want do isolines and set interval between isolines

isolines

Smoothing

Tool is used for make smooth operation for selected raster layer. Factor mean how many times this process will be repeat.

smoth

Cut raster

Tool is used for cut selected raster layer with selected one feature polygon layer

cut

Tools

Load Legend

For active raster layer user can download predefined raster legends stored in Clidata database

Export

Export map to PNG

exportPNG

Used can export map into image file in format PNG by using this tool. Where:

  • Map Title is title for your map
  • Legend Title is title in legend of raster legend like [C°]
  • File is filename for your map in PNG format
  • DPI is resolution for image file

Export to Raster

Tool will export selected raster layer into Erdas Imagine format .img with symbology layer .lyr into user's defined directory exportRaster

Settings

User can in this part to define area for clipping display in map and in case user can define different DEM (digital elevation model ) than default.

Cancel Clip Geometry

Tool cancel user defined geometry for clipping map frame

Set Terrain

User can change default (DEM\dem.asc) digital elevation model to your own. DEM file have to be in ascii grid format (*.asc)

Set Frame Clip

User can choose for active polygon layer geometry by click on map, which will be used for clipping map frame
