1 CUSTOMISED QGIS for Forest Change Detection
Good morning My name is Naomi Jackson. I’ll be speaking shortly on what I have been doing as a a member of the GIS team in SOPAC. Customization of QGIS. What is QGIS?? Open Source Software with GIS apps that provides data viewing, editing, and analysis capabilities 2) Quantum GIS - Is a free software desktop Geographical Information System (GIS) application that provides data viewing, editing, and analysis capabilities.

2 WHAT QGIS? Open source GIS software (GIS) application that provides:
data viewing, editing, and analysis capabilities It’s Simple SPC supports

3 QGIS History & New?? Version 0.0.1( July 2002)
Version 1.8 ( June 2012) QGIS 1.8 has additional features: QGIS Browser QGIS Cloud DB Manager Some new features include: - QGIS Browser - a stand alone app and a new panel in QGIS. The browser lets you easily navigate your file system and connection based (PostGIS, WFS etc.) datasets, preview them and drag and drop items into the canvas. - DB Manager - the DB manager is now officially part of QGIS core. You can drag layers from the QGIS Browser into DB Manager and it will import your layer into your spatial database. Drag and drop tables between spatial databases and they will get imported. You can use the DB Manager to execute SQL queries against your spatial database and then view the spatial output for queries by adding the results to QGIS as a query layer

4 New?? QGIS 1.8 has additional Plugins: Terrain analysis GPS tracking
MSSQL Spatial Support Heat map tool Customization etc… Terrain Analysis Plugin - a new core plugin was added for doing terrain analysis – and it can make really good looking coloured relief maps. GPS Tracking - The GPS live tracking user interface was overhauled and many fixes and improvements were added to it. MSSQL Spatial Support - you can now connect to your Microsoft SQL Server spatial databases using QGIS. Heatmap tool - a new core plugin has been added for generating raster heatmaps from point data. Customization - allows setting up simplified QGIS interface by hiding various components of main window and widgets in dialogs.

5 QUANTUM GIS Easily Add Vector Layers
Link to external Database and import database Display Information on each Island/Atoll Automatically change Properties (different colors for different land cover) Once the Layers and the database are in Compatible formats of QGIS Quantum GIS allows use of shapefiles, coverages, and personal geodatabases. MapInfo, PostGIS, and a number of other formats are supported in Quantum GIS

6 Projects Vegetation cover Low-Lying Islands (Kiribati and Tuvalu).
Vegetation cover Viti levu Forest change detection & Why am I using MAPINFO and MapBasic. This is because

7 Software QUANTUM GIS (QGIS) – Open Source PYTHON MAPINFO 10.0
MAPBASIC 10.0 Why am I using MAPINFO and MapBasic. This is because

8 Currently Data Transfer…
MapInfo Quantum GIS I am taking a project that has been customized in MapInfo into QGIS. SOPAC has completed Customizing the Forest change detection display of What I have been working on is Customized display in QGIS

9 VECTOR LAYERS MAPINFO QGIS .TAB .SHP RASTER .TIFF .IMG….etc
A couple of points I had to consider in QGIS is that IT can read .Tab files but converting it to shape files is a more compatible format for QGIS. I convert using the Tools and then universal translator in MapInfo.

10 Database.... MAPINFO QGIS .mb .csv Export Microsoft Access MDB to CSV
QGIS reads .CSV (Comma Separated Values ) files. What I do is I export the access files using an open source exporter (Frontier DG)

11 DATABASE… QGIS reads .CSV (Comma Separated Values ) files.
What I do is I export the access files using an open source exporter (Frontier DG) to CSV and then create a link through SQL( Structured Query Language).

15 Kiribati_Christmas Island
Automatically change Properties (different colors for different land cover) It can also display a legend showing the different vegetation cover.( Print Compose Manager)

16 Tuvalu_Vaitupu

17 NOW… Writing custom applications (PYTHON)
Creating web displays of work done in QGIS making it available on Web through Geo-node ,QGIS server etc Creating web display with layers prepared in QGIS…..trail run QGIS Cloud and QGIS server.

18 FUTURE PLANS Customize Quantum GIS and Install with SPC (GIZ ,FAT Department) Migrate all spatial layers to PostGIS Migrate all tabular data to PostgreSQL Documentation on SOPAC website What are my Future Plans?? Customize QGIS and Install with SPC LRD (Forest and Trees).
