| | | Review of the literature is an essential starting point for any endeavour in GIS, remote sensing, or mapping. Yet, reviews are often incomplete for lack of access to the material, and consequently projects experience durations that are longer and costs that are higher than need be because the accumulated knowledge has not been tapped and taken advantage of. This page sets out to mitigate that problem. It is a gateway to the literature that represents much of the accumulated global experience on using GIS, remote sensing and mapping to solve problems and issues in aquaculture and inland fisheries. Spatial issues addressed most frequently for aquaculture and inland fisheries are listed in two tables in issues section along with the number of literature records currently contained in GISFish databases. Four recent studies available for download in issues section provide background information on GISFish databases. | | | |

| | | Title | A practical guide to geostatistical mapping of environmental variables (free publication) | | Description | Geostatistical mapping can be defined as analytical production of maps by using field observations, auxiliary information and a computer program that calculates values at locations of interest. Today, increasingly the heart of a mapping project is, in fact, the computer program that implements some (geo)statistical algorithm to a given point data set. Purpose of this guide is to assist you in producing quality maps by using fully-operational tools, without a need for serious additional investments. It will first introduce you the to the basic principles of geostatistical mapping and regression-kriging, as the key prediction technique, then it will guide you through four software packages: ILWIS GIS, R+gstat, SAGA GIS and Google Earth, which will be used to prepare the data, run analysis and make final layouts. These materials have been used for the five-days advanced training course “Hands-on-geostatistics: merging GIS and spatial statistics”, that is regularly organized by the author and collaborators. Visit the course website to obtain a copy of the datasets used in this exercise. | | Content Language(s) | English | | Keywords | AQUACULTURE INLAND FISHERIES | | Download | | | Date | 03 January 2009 | |
