Plan4all implementation in Malta

Fondazzjoni Temi Zammit 2011-01-31

Introduction

Fondazzjoni Temi Zammit (FTZ) engaged the help of the Topographic Product Development (GI-Related) Management at the National Mapping Agency within Malta Environment & Planning Authority (MEPA).

MEPA has been working on issues like European wide homogeneous data sets emphasizing on land cover topics for several years.  Land cover plays an important role for environmental spatial and territorial analysis.  Up-to-date data about land use and land cover is maintained at very high detail, nominally at 1:1000.  In view of such detailed-scale usage, maps at scales required by Corine Land Cover are rarely used due to the generalized product that is not used for local consumption.  This project required the acquisition of satellite imagery and photo interpretation methodologies for the main CLC2006 map and the 2000-2006 change analysis.  Data sources that were used in conjunction with the EEA/JRC imagery included the national maps and ancillary data that include orthorectified imagery (2004), topographic maps, land use-maps as produced for local plans, habitats, agricultural, environmental datasets, and development planning parcels, amongst other datasets.

Malta is the smallest European Union member state both in terms of area and population size.  It is situated in the central Mediterranean sea about 100 km south of Sicily.  It consists of an archipelago of three main islands, namely Malta, Gozo and Comino, as well as a number of smaller uninhabited islets, for a total area of 316 sq. km.  Malta’s terrain consists of low hills with terraced fields, alternating with fertile valleys.  The population of the islands stands at 430,000, making Malta one of the most densely populated countries in the world, with about 1,360 inhabitants per square kilometre.  Malta constitutes a total of 68 municipalities, most of which are exceedingly small.  The islands are notable for their unique historical and cultural heritage, as well as their maritime traditions in connection with their strategic position in the central Mediterranean and their fine natural harbours.

Architecture

In order to prepare spatial data for publication, FTZ has developed a conceptual approach for data compilation as follows:

  • Content Providers identified
  • Diverse Entities & Organisations
  • Various datasets:
  • CorineLandCover
  • Special Protection Areas (SPAs)
  • Special Areas of Conservation (SACs)
  • Development Zones

      

Figure 2‑2            Overview of FTZ Conceptual Approach

FTZ has decided to apply previous work done on the Maltese Islands as a case study for the Plan4all project.  The case study comprises data and metadata related to the Plan4all theme of Land use.  A conceptual metadata model has been defined, which model complies with national and international standards.  An OS software application was adopted and implemented for the publishing of online CSW services.

 

Metadata Compilation

The datasets for metadata testing were Corine Land Cover 2000 - CLC2000 and Corine Land Cover 2006 – CLC2006.  Meatadata of the spatial planning data was created and compiled by INSPIRE Metadata Editor (XML Creator).  The INSPIRE Metadata editor makes it possible to create INSPIRE compliant metadata and to download it as an xml file.

Data (GeoServer)

The web interface selected for testing WMS and WFS services was GeoServer.  This is an open-source server application that enables sharing and editing of geospatial data.  It is designed for interoperability, and publishes data from any major spatial data source using open standards.  It is an easy application for connecting existing information to Virtual Globes such as Google Earth and NASA World Wind, as well as to web-based maps such as OpenLayers, Google Maps and Bing Maps.  GeoServer reads a variety of data formats, and through standard protocols it produces KML, GML, Shapefile, GeoRSS, PDF, GeoJSON, JPEG, GIF, SVG, PNG etc.
