Red List Tools For ArcGIS10 v 20110504

This toolset is created to automate some of the most commonly performed GIS tasks in the RedList unit for spatial data. Details of each tool are explained as follows (the same documentation as well as input field explanation can be found in tools):


1.      Add owner field

Add owner field to the data to be submitted to the spatial database. This should be done only when submitting data to a database which has kept a record of ownership such as the central species GIS database.


2.      Check SIS and spatial database for submitting data (beta)

It appends species records from an input layer to a destination layer only if 1. the species does not already exist in the destination layer and 2. the species has an assessment in SIS. This script is specifically used for adding NEW species to the species GIS database. Please note:

  • All spatial data quality checks should be done prior to this tool. (‘check species data before submission’ tool in the Red List toolbox can be used for doing this)
  • All spatial data must have owner field filled by using 'Add owner field' tool
  • Species IDs will be extracted from SIS and added automatically to the spatial data

This tool is still beta version due to the fact that the backend SIS database (based on postgres) has not been finalised and all hard-coded queries in the script rely on its table structures.


3.      Check species data before submission

This tool checks 1. Spatial reference (it has to be WGS84 Geographic) 2. Required fields (all necessary fields, details can be found in the species mapping tools) 3. Geometry (should be free of geometric errors)4. Simple field statistics


4.      Clip to base (vector)

This tool is used to clip any vector layer to a given layer specified by user input. It is usually used for batch clipping all vector layers in a map document referencing data from the central GIS Basedata server so that they can be clipped for a particular area of interest and take them to workshops. This tool is usually used in conjunction with ‘8. Replace data source from clip workspace’.


5.      Compare species list against spatial data

This tool can be used to compare a list of species against species spatial data to find out what species have/don't have spatial data. It also creates a log file under the workspace, which you can change in the environment settings


6.      Compare species list against spatial data and export selection

This tool can be used to compare a list of species against species spatial data to find out what species have/don't have spatial data. After that, species found in the spatial data will be exported to a feature class/shapefile specified by the user


7.      Produce map from a map document (mxd)

This tool is used to create maps from map documents. It will create a map from whatever the layout view shows. This tool is usually used as batches and useful in situations where a map of multiple formats and resolutions for a same map document are needed.


8.      Replace data source from clip workspace

This tool is usually used in conjunction with '4. Clip to base (vector) tool’, fixing broken data sources that are linked to central database whereas they should be linked to the clipped data.


9.      Simple field statistics

This tool calculates uniques values in a given field and counts the number of unique values.


10.  Update binomial

Update binomial name based on the input text file. Note: 1. the text table has to be separated by comma. The format of the text file is IMPORTANT and it can be found in the tool description 2. CAUTION! Make a copy before running the tool (it will make changes to the original shapefile!)

Please read the instructions on each field input carefully when using the tool.


11.  Zoom to species

This is NOT intended to replace the Speciesbrowser, however, this tool can be used such that geoprocessing models can be created to incorporate zooming capacity for automated mapping. For example, it can be used together with '7. Produce map from a map document'.
