<p class="MsoNormal">Dear developers,<br>
<br>
Please find below a detailed Request for a Proposal and
Quotation for an AILUM (Agriculture Inventory and Land Use
Mapping) plug-in for QGIS.<br>
The tender is being announced by GTZ (German Technical
Cooperation).<br>
Note that the deadline for submission is the 04-Feb-2011, and
the award date is 15-Feb-2011.
<br>
Please feel free to contact Ricardo Aravena (<a
moz-do-not-send="true" href="mailto:ricardo.aravena@gtz.de">ricardo.aravena@gtz.de</a>)
if you have any questions regards the technical specification
and the tendering/bidding process.<br>
<br>
<b>Organizational Overview </b><br>
The Deutsche Gesellschaft für Technische Zusammenarbeit (German
Society for Technical Cooperation) or GTZ is a private
international enterprise owned by the German Federal Government,
specializing in technical cooperation for sustainable
development with worldwide operation. It primarily works for
public sector organizations and is headquartered in Eschborn,
Germany. It mainly operates on behalf of the Federal Ministry
for Economic Cooperation and Development (BMZ). Further clients
are other departments of the government, international donors
like the European Union, World Bank or the United Nations,
partner countries and the private sector. GTZ works on a
public-benefit basis. All surpluses generated are channeled back
into its own international cooperation projects for sustainable
development. The GTZ provides services in the following areas of
sustainable development: Economic Development and Employment;
Government, Democracy and Poverty Reduction; Education, Health
and Social Security; Environment and Infrastructure &
Agriculture, Fisheries and Food.<br>
<br>
<b>Required Deliverables</b><br>
A QGIS plugin for an automated process to manually classify land
types from satellite imagery for land use mapping based on
visual identification.<br>
<br>
<b>Function</b><br>
To avoid high-level academic training of remote sensing
classification techniques, an easy, yet robust method of
classifying land types simply by clicking on them from visual
identification as a non-expert would from a common application
like GIMP is required. The idea is that non-experts would be
able to conduct their own land use mapping. The areas from the
resultant vector land use maps produced would be further applied
to calculate indicators such as expected crop yield.<br>
<br>
<b>Target Users </b><br>
The tool is principally intended for an agricultural inventory
project to be conducted by provincial staff from the northern
Laotian province of Luang Namtha, though it would also be useful
for some Participatory Land Use Planning and other mapping
activities across other provinces in Laos. Thus it needs to be
as simple and automated as possible.<br>
As it is intended to be an Open Source tool under GNU (general
public use) license, it could also potentially be used by anyone
with an internet connection and QGIS. It would serve well in the
development context where funding, expert knowledge and training
is limited. <br>
<br>
<b>Technical Specification</b><br>
A Python plugin is to be coded for QGIS as either a new Menu
tool set, Panel or Toolbar.
<br>
The plugin will have 3 parts:<br>
1. Imagery preparation – this will automate 4 steps: <br>
(i) conversion of images to 8 bit Geotif (if necessary), <br>
(ii) creation of a georeferencing tag file (.gtf), <br>
(iii) Equalization, <br>
(iv) then Blur. <br>
The user will simply be asked where to store the new files for
the image and then the steps will be run in sequence
automatically.
<br>
2. Classification – <br>
a) Visual classifications of distinct, contiguous recognizable
land types are to be conducted on the standard QGIS map
interface the same way it would be done in a program like GIMP
with BOTH the ‘Fuzzy Select Tool’ and the ‘Select by Color
Tool’. The users will apply these tools on a trial-and-error
basis with similar dynamic ‘Threshold’ slide bars as in GIMP’s
interface until they are satisfied with their selections.
<br>
b) A third tool would also be necessary to group or generalize
the user’s selections, the way ‘Select>Border’ would do in
GIMP.<br>
c) A dialog should appear on request every time the user is
satisfied with their selection to render the land types with an
appropriate colour and assign a textual label which will be
included in a landuse field. The colours and texts should be
editable and not limited in number. This label and colour
information may somehow be embedded in the image or stored
separately in a look up table if necessary so that it can be
rendered accordingly in the resulting end-product vector
shapefile.<br>
3. Vectorization – this will polygonize the classified image as
contiguously as possible to a shapefile. And the landuse and a
colour fields generated in the precious step will need to be
either maintained or associated correspondingly to the
shapefile.<br>
<br>
It is proposed that:<br>
- The conversion of the imagery to 8 bit Geotif and the creation
of a tag file could be done with GDAL commands.<br>
- The Equalization and Blur need to be produced with the same
effect and quality as that produced by GIMP’s
Colors>Auto>Equalize and Filters>Blur>Gaussian Blur
respectively; however since GIMP’s libraries can only be run
internally from within GIMP, it is proposed to implement the
equivalent functionality from ImageMagick’s libraries instead.<br>
- The same goes for the ‘Fuzzy Select Tool’, ‘Select by Color
Tool’ and ‘Select>Border’ GIMP equivalents.<br>
- The vectorization could be conducted by the GDAL polygonize
function for example as long as its parameters can be set to
produce contiguity to reduce individual pixelization.<br>
- Step 2b), the most challenging, could be catered for in many
ways and so will be left up to the solution provider’s
discretion. Use of the already translated Orfeo Toolbox
libraries is encouraged.<br>
<br>
This is the proposed construction and presentation for the
plugin, however if applicants present a better workflow or
methodology this will also certainly be considered and in fact
favored.
<br>
<br>
<b>Assumptions & Agreements </b><br>
- The name of the plugin shall be “AILUM (Agriculture Inventory
and Land Use Mapping)”.<br>
- The plugin needs to be a completely Open Source solution with
no legal infringements.<br>
- After being tested, the plugin and its code will be publicly
available under GNU license as FLOSS.<br>
<br>
<b>Technical Proposal </b><br>
The solution provider should include time-lines and schedules
for completing the project.
<br>
<br>
<b>Time-Cost </b><br>
The solution provider must detail the time and costs that will
be required to complete the project.
<br>
<br>
<b>Additional Documentation</b><br>
Developers can direct us to an internet site or repository which
demonstrates their production capabilities.
<br>
<br>
<b>References </b><br>
References are optional, though preferable if the candidate is
not a company with a published track record.<br>
