Geospatial framework for GIS and geoportal
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.
