Thank you for participating in this
SDSU/NASA project. This web site (http://map.sdsu.edu/arc) is
used to develop web-based geospatial information services for the
purpose of natural habitat conservation and management. Three
distinct web service functions are integrated into the prototype,
an on-line data warehouse is developed for archiving, accessing and
downloading GIS databases and remotely sensed imagery, multiple
internet map servers are established to provide web-based map
function capabilities, Java-based on-line analytical tools are
implemented for high resolution imagery visualization, comparison,
analysis and improved interpretation of change detection. To
better serve you walk-through the web site, two tutorials are
created as follow links
Tutorial 1 (649k),
Tutorial 2 (1180k).
We are seeking input from
professionals such as yourself, to help us refine these on-line
tools and web user interfaces. Your comments and insights are
valued and important to us, and this project will be benefit from
evaluation by experts like you. Thank you for participating. |

Part 1. Data
Warehouse |
| |
|
1. Please rank the following tasks of
data warehouse services to indicate the importance to your job. |
|
Very Important |
Important |
Not Important |
N/A |
| 1) View
the thumbnail images. |
|
|
|
|
| 2) View
the metadata descriptions. |
|
|
|
|
| 3) Download
the image/data sets |
|
|
|
|
| 4)
Search/Query data set. |
|
|
|
|
|
|
|
|
|
|
|
|
2. What do you like
and do not like the data warehouse? ( Please specify in functions, user interfaces,
data contents or others? ) |
|
|
|
|
3. Are you satisfied with the
web-based data warehousing? can you successfully search and
retrieve the geo-spatial data sets? Do they provide enough
information you want? |
|
|
|
|
|
Part 2.
Internet Map Server |
|
|
|
1. What
do you like or dislike the interactive map? (functions/user
interfaces/data contents/others?) |
|
|
|
|
2. Do you like the performance of web-based software
ArcIMS? What is the advantage and disadvantage of ArcIMS for web
mapping facilities? |
|
|
|
|
3. From your own experience, what are the
differences between traditional GIS ( such as ArcView and ArcGIS )
and web-based GIS ( ArcIMS )? |
|
|
| |
|
Part 3. On-line
Analytical Tools |
|
1. Current prototype web site hosts eight
on-line analytical tools
listed below. Please rank the usability of these tools. |
|
Excellent |
Very Good |
Good |
Fair |
Poor |
| 1) Image Overlay |
|
|
|
|
|
| 2) Image Swipe |
|
|
|
|
|
| 3) Image Magnifier |
|
|
|
|
|
| 4)

|
|
|
|
|
| 5)
Image Viewing |
|
|
|
|
|
| 6)

|
|
|
|
|
|
|
|
|
|
|
| 2. Which
on-line analytical tool do you prefer most, which one least prefer? Why?
What is the limitation and improvement for these toolkits
(functions/user interfaces/data contents/others)? |
|
|
|
3. How
well do you consider to adopt these web-based analytical tools for
remotely sensed imagery in tracking natural habitat conditions
and status of preserves? |
|
|
|
|
4. How
well are you able to visually interpret the change of land cover
on the two
change detection products (image overlay and image swipe)? |
|
|
|
|
5. Can
you think of any functions that are missing in the on-line
analytical tools? |
|
|
|
|
Part 4. General |
|
|
|
1. Please provide your comments on overall
performance, information contents, design and the structure of
this web site. |
|
|
|
| 2. How
well do you feel the Internet as a tool for transaction with
geo-spatial information? Do you think that the prototype and
Internet in particular will alter and substitute the traditional
approach for transferring large quantities of data to the
targeted users? |
|
|
|
|
3. Will you consider that the web-based
analytical toolkits developed by this prototype have potential
value for the purpose of your organization, will they be
cost-effective tools to monitor natural habitats and reduce the
labor of field monitoring? |
|
|
|
|
4. Are you currently using any web-based GIS
products? If yes, how well do you like it compared with the tools
developed by this prototype? |
