November/December 2010: Final workshop

The final ENDELEO workshop was organized on November 30th and December 1st 2010 in Nairobi. The first day of this workshop time was dedicated to the demonstration of local applications for which the ENDELEO tools have been a valuable source of information. Case studies were presented by the users. It was an ideal opportunity for the users to raise awareness on the topics they are working on. The contributions could inspire other users and ideas between users can be shared.
The secodnd day of the workshop consisted of a basic remote sensing training: the use of the ENDELEO tools and ENDELEO data handling in ArcGIS.

May 2010: DEMO ENDELEO Tools

The aim of the visit in May 2010 was to create or increase interest in the use of RS for environmental monitoring and to explain how ENDELEO tries to lower the barrier for its use. It was also an opportunity to enhance the ties with users previously involved in ENDELEO. A demonstration workshop was given at the Department of Resource Surveys and Remote Sensing (DRSRS) in which representatives from eight different Kenyan institutions participated. A brief introduction to the project and a demonstration of the web‐based tools was given, after which the potential use of low resolution vegetation indicators (e.g. NDVI and DMP from SPOT‐VGT) was illustrated. The response from the participants was very positive. Besides, six different organizations were visited: Regional Centre of Mapping of Resources for Development (RCMRD), Kenya Forest Working Group (KFWG), Save the Elephants (STE), Kenya Wildlife Service (KWS), International Livestock Research Institute (ILRI) and the International Union for Conservation of Nature (IUCN). At each organization potential contribution of the ENDELEO tools for their activities was discussed.

April 2010: Smoothed graphs available

The information displayed in the graph function has been changed. In the previous version, the graphs were based on the values directly calculated from the NDVI images. However, fictitious minima may occur e.g. due to undetected clouds. In the new version, the NDVI values are smoothed over time. The smoothed value is calculated as the average value of the two previous decades, the decade itself and the two next decades. In this way, it removes all abrupt local minima (supposedly clouds), as far as they don’t persist longer than four decades. As such, three graphs are plotted (see figure below). The red graph shows the temporal evolution of the NDVI (vegetation health & density) for the selected year, directly calculated from the images. The blue graph is representing the same, but the dataset has been smoothed over time to remove possible dips related to bad values. It is better to interpret the change of the blue graph than of the red graph as the overall trend of the values becomes more clear after removing small changes that are not due to the trend. The black graph shows the smoothed NDVI for the ‘average year’. The ‘average year’ corresponds to the ten year average (1999-2008) NDVI. Comparing the position of the blue graph with the black graph shows whether the vegetation conditions for the year of interest are better or inferior compared to the average situation. If the blue graph is above the black one, the conditions are better, if it is bellow, the conditions are worse.

February 2010: Toggle on/off vectors in image viewer

A new functionality is added to the image viewer of the monitoring website to switch on or off three different layers: districts, protected areas and NRT conservancies (see red rectangle in the figure 1 below). By toggling on these vector layers, the corresponding borders appear on the image.
During the last workshop in Nairobi April 2009, it was suggested to add besides these three layers also roads, villages, rivers/lakes, boreholes, cropping areas, wildlife corridors and constituencies. In the near future, the feasibility for gathering and implementing these features will be examined.
