7) Corona photos
The server for the archive photos from the Corona missions is located at
the following (new) address: http://earthexplorer.usgs.gov/
>TEMPORAL COVERAGE
>Start Date: 1960-08-18
>Stop Date: 1972-05-31
These are analogue satellite photos whose negatives can be enlarged up to
the scale of 1/16 000 with a resolution which is close to aerial
photography. The photos were taken during the years 1960s. It can be very
useful for researchers who have to study land use evolution between 1960
and now.
8) Mapping service on the web
On the search engine Google, for street addresses in North America. Example
: to know where 165 Mariposa Avenue in Los Angeles is located.
http://www.google.com/help/features.html
Find Maps with Google
9) Automatic cartographic generalization
One article in the French IGN-Magazine magazine, issue 5, May-June 2001,
related to automatic cartographic generalization at the scale of 1/250 000.
10) Idrisi32 COM-programming
On the webpage http://www.clarklabs.org/13dnlds/32apifrm.htm, I have
realized it is possible to program Idrisi modules through a language
likeVisualBasic
Note: this is possible in version I32.02, though there is no mention in the
online help documentation!
>IDRISI32 is 100% COM-Compliant -- Access the power of IDRISI from any
programming environment (e.g., VB, >Delphi, C++) to create your own custom
applications, such as Dynamic Modeling and Cellular Automata.=20
11) Online cadastres
The small French commune of Gluiras in Ard=E8che has a real online cadastre
like Santa Monica in Californie:
http://www.gluiras.com/
(Source : magazine "Internet Today le Web", issue 10, April 2001.)
Other cities with cadastre web services are :
---------------------------------
In Canada, at least one province (New Brunswick), some cities like Aylmer
in Qu=E9bec and the neighbouring ones in the same county
(http://www.ville.aylmer.qc.ca), as well as about one hundred other cities
in Northern America: Redding, California (http://maps.ci.redding.ca.us),
Dublin, Ohio (http://gis.dublin.oh.us/), Mason County
(http://hq.carlsonsw.com/ plot mapping with tax information) Oakland,
California City maps (with a Crime Watch applet at
http://www.oaklandnet.com/maproom/default.html). Natural Resources Qu=E9bec
is preparing an online provincial cadastre in the near future.
In Uruguay, Montevideo
(http://www.cvision.com.uy/MapGuide/Montevideo/montevideo.htm)
In France, Issy-les-Moulineaux, Nice (http://www.plan-nice.org/cadastre),
Laval (vector data and ortho-photos http://www.mairie-laval.fr/)
In Switzerland, a complete cartographic site for the state of Fribourg
(http://www.fr.ch/ville-fribourg/friweb/default.asp)
In the Netherlands : Utrecht (raster data at=
http://gis2.info.nl/bodemloket/)
12) Availability of public data in Europe ?
One article written by Monsieur Charles de Laubier <claubier@lesechos.fr>
in Finantial Times, Connectis, page 42, June 2001, on the famous issue of
"non-availability" of essential geographical informations.
13) Wireless optical networks
Two American companies provide wireless solutions for the dissemination of
numerical data by laser beams up to a distance of 4 km.
fSONA Optical Wireless Systems (Richmond, British Columbia, Canada)
http://www.fsona.com/html_version.htm
http://www.fsona.com/news/news-09.htm
Retail price of the SONAbeam 155-2 system is $30,000 and includes both ends
of the optical wireless link. Other products, including the SONAbeam
155-SH system for distances up to 500 meters and the SONAbeam 622-2 which
transmits 622 megabits per second over 2 kilometers, will ship later this
year.
Optical Access
http://www.opticalaccess.com/
The TereScope=99 family of products allows high-speed wireless connectivity
in a number of last-mile applications. Operating at data rates of 1 Mbps to
1.25 Gbps, TereScope=99 solutions provide a scalable wireless alternative to
leased lines.
14) A GPS wristwatch

" New version of the model, smallest and lightest of watches GPS, Satellite
Casio Protek Navi PAT2GP-1V, uses the network of satellites GPS to indicate
your position to you. Casio PAT2GP-1V is delivered with a software of
management of the positions and routes which enables you to enter the
starting point and of arrival of your voyage as well as the stages and to
transfer the data thus recorded towards your watch. Information recorded
by the watch during the voyage can also be transmitted to the software in
order to optimize calculations. Essential to the hikers and the navigators.
Technically, acquisition is done in 15 second surroundings with precision
of approximately 10 meters.
