Basics of geoportals
Geospatial base data received as a result of remote sensing and digital
vector
card. Basis any geoinformation system is the spatial data that are
essential for successful management of territorial objects and processes. The
most promising direction in modern conditions is to use as a base for GIS data
of Earth remote sensing (ERS).Traditional means of remote sensing data require
end-users certain knowledge of the technologies of their processing, as well as
the cost of time on the processing of large amounts of computer memory to store
them. If the ultimate goal is the visual interpretation and analysis of
satellite images, the more productive is the online access to structured
repositories of remote sensing data located on servers distributors. This
method of obtaining data can increase the speed and convenience of access to
the latest geospatial base, which is constantly updated on the portals and data
providers remote sensing of the earth. One of such variants remote
online access to spatial data is the archive of high-precision remote sensing
data . The service should provide online access to the archive of satellite
imagery data and allow to save the picture for use in modern GIS-applications
(ArcGIS, MapInfo, AutoCAD and others). Service for the use of data at any
mobile devices connected to the network. Internet
important advantages of this method of access to spatial basis are: multi-user
access to the database of the latest space images; conserve disk space; providing
secure access to remote sensing data; use of data in mobile устройствах.В during the
implementation of the project on creation of GIS formed a single database and
common object model of spatially-distributed resources that are used by all
users of GIS in accordance with the applied nature of functional tasks in their
subject area. Toolkit GIS can be used to solve the tasks of asset management.
The Toolkit uses the following technologies and methodology of work: to
formalize the requirements of the Customer;
on the acquisition of data; data processing; mass input of data into the
database; updating data in the database; according to expert estimates of the
database; modeling and forecasting of the processes and phenomena; creation of
the automated workplaces for decision-makers in their own subject areas in the
system of management for enterprises. To achieve this goal the following tasks:
1. develop and justify the methodical approaches
to the development of GIS;
2. to create a unified informational basis tasks
of engineering hydrology - a universal digital terrain model;
3. to develop the algorithms of structuring the
area, element-by-element calculation of its characteristics and to assess the
impact of sampling rate and scale of initial data for correctness of
calculation;
4. build a universal model of GIS for solving
the problems;
5. develop domain-specific software solutions
for implementation of GIS applications;
6. test the created GIS applications.
The Ministry of health is required picture of
the availability and distribution of medical institutions, and statistical data
on the distribution of morbidity in cartographic modeling allow to make a
number of significant findings in relation to existing environmental problems
and the causes of sickness important.
