Записки программиста, обо всем и ни о чем. Но, наверное, больше профессионального.

World Elevation Services

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

Конференция ну прям по теме Крымска

Flood Modeling
Level:
Intermediate
Date/Time:
Tue, Jul 24, 8:30AM - 9:45AM
Location:
Room 25 C
Description:
This session presents approaches to river, storm, and storm surge flood modeling.
Papers:
A GIS Flood Tool for Rapid Inundation Mapping



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 Крымском?
