Отметки высот,
рельеф, склоны — как недавно убедились
все (все знают про Крымск?), это очень
важные сведения. Имея доступ к таким
данным на нужную территорию, можно
смоделировать ситуацию. Как сброс воды
из водохранилища, так и сток ливневых
вод со склонов.
И лучше проводить
такое моделирование до катастрофы а не
после.
А теперь о
хорошем: Esri открывает доступ к огромному
массиву данных по высотам и рельефу
Земли
Elevation data is an
essential piece of GIS data for hydrologic applications, but it’s
big, not always easy to get and for modeling surface water flow
requires specialized processing to become useful. Elevation data and
services are coming to ArcGIS Online, including some hydro specific
capabilities.
World Elevation
Services
The World Elevation
Services became available for beta testing last fall and will be
released at the end of March. There are image services, data download
services, and analysis task services available, as well as sample
applications. The services are built from a collection of data
sources, ranging from less than a meter resolution up to almost 5
kilometers, and includes services of elevation, shaded relief, slope,
and aspect. We will continue to add new data as it becomes available.
Like other things on ArcGIS Online these services can be used in
Desktop and any other Esri clients, and also in other applications
via REST or SOAP

А вот и он,
сервис:
The World Elevation
services provide simple, online access to global collections of
multi-resolution, multi-source elevation data. This collection
includes data with resolutions ranging from approximately 1 kilometer
to less than 1 meter. The services provide a single endpoint for
desktop and web applications to access elevation values and derived
products.
You can use these
services in your desktop and web applications:
As information
layers, such as a hillshade or aspect
To orthorectify
imagery
As a data source
in your analysis models or other geoprocessing tasks
To obtain data
locally
Что, кто
возьмется смоделировать ситуацию с
