Image Processing course

• New image processing course will be added to the
  Landmap site. It will cover the following modules
• Using contrast manipulations to reveal the
  pattern of major weather systems
• Land Cover Assessment using a Multispectral
  Colour Composite Image
• Spectral Mapping
• Georeferencing images
• Structural mapping
• Vegetation mapping
• Land Cover Classification
• Land Cover Classification
• Meteorology and sea-surface temperature mapping
• Coastal mapping
• Integration with GIS - Landslide Susceptibility
  mapping
• The course instructions are now available in PCI
  format, Erdas Imagine, ENVI and soon will be
  available in Idrisi or ERMapper.
• It is hoped that by the new academic year the
  course will be available as a E-Course to be
  directly input into Virtual Learning Environment.

Satellite Image Data Service

• Supports a large geographic data resource
• Require CHEST license and payment of a JISC data
  hosting charge.
• Web-based access to a range of satellite imagery
  for the British Isles for research and teaching
  purposes
• Landmap Datasets
• Infoterra Satellite Data Archive
• Mediterranean data
• New ENVISAT Datasets
• Image processing course
• New download interface to access the Landmap data
  products.

New mapping interfaces to Satellite data

• JISC funded Interoperability demonstrator project
  in collaboration with EDINA, UCL, University of
  Leeds and NERC DAC.
• We will produce OGC WMS services, Using Image Web
  Server (IWS) from ERMapper. We are also using of
  University of Minnesota MapServer to produce IWS
  and WCS services.
• We currently are also developing ECWP streaming
  and ARCIMS compatible services. Using IWS. We
  hope to bring into service at some time. Through
  browser or ArcExploere type.

Landmap

• Output datasets (satellite data in both strip and
  mosaic formats)
• 1 (25m) Digital Elevation Model product (WGS84
  and OSGB National Grid) in House production
• Kinematic GPS profiles for quality assessment of
  DEM and geocoded products( In house)
• Orthorectified archive of ERS-SAR amplitude and
  phase coherence data-strips
• Orthorectified archive of LANDSAT 30m and SPOT
  10m data
• Mosaic of orthorectified IfSAR, LANDSAT SPOT
  products
• ENVISAT data
• Mosaics of the above
• Image Processing Course

ENVISAT Data

• JISC is also funding as part of the development
  of the Landmap service the purchase and
  processing of multi-season Envisat data.
• The project to acquire and process the data will
  start in the next few weeks.
• Data will be processed and made available through
  the Landmap service

New ENVISAT Data Advanced Synthetic Aperture
Radar

• ASAR imagery, British Isles coverage, GB National
  Grid and Irish Grid Coordinates.
• Provided in WMS and WCS services for
• Image Mode (IS2 Swath),
• Alternating Polarisation,
• Wide Swath
• Future Work
• Provide data at different times of the year
  seasonality
• Create Coherence Colour Composite Multi Images
  and interferograms.
• Provide on-line learning support materials for
  ASAR data

• JISC funded Interoperability demonstrator project
  in collaboration with EDINA, UCL, University of
  Leeds and NERC DAC.
• We will produce OGC WMS services, Using Image Web

  investigating the use of University of Minnesota
  MapServer to produce IWS and WCS services.

• Another product for serving imagery is Image Web
  Server 7.0
• Image Web Server provides ECW high speed
  streaming for all Landmap imagery and also serves
  OGC WMS
• ECW streamed imagery can be accessed at

The Google Earth/Maps evolutionary pressure

• Pressure
• High user expectation of High resolution images
  accessed in a Google like interface
• Evolutionary response
• Provision of high Quality, high precision data,
  via web interface that allows interoperability!
• Access to real data not just images
• Access to learning resources and expertise
• Access to a variety of data, such as LIDAR, low
  resolution weather data, seasonal variations,
  weather and various monitors of the environment
  not just aerial photography.
