An Approach to Develop a Geographic Information Database Using Dot Spatial Open Source Platform and Google Search Engine
نویسندگان
چکیده
Data is the core of Geographical Information System (GIS). Collecting and updating geographically referenced and descriptive data is necessary for GISs. Ignoring the updating process will obviously decrease the usefulness of GIS; therefore, GIS databases must be updated to make better use. There are different methods to collect and update GIS data, for example, by field survey, remote sensing, digitizing, or by analyzing old data to produce new data.

Implementing an open source spatio-temporal search platform for Spatial Data Infrastructures
A Spatial Data Infrastructure (SDI) is a framework of geospatial data, metadata, users and tools intended to provide an efficient and flexible way to use spatial information. One of the key software components of an SDI is the catalogue service which is needed to discover, query, and manage the metadata. Catalogue services in an SDI are typically based on the Open Geospatial Consortium (OGC) Ca...
متن کاملVHR Semantic Labeling by Random Forest Classification and Fusion of Spectral and Spatial Features on Google Earth Engine
Semantic labeling is an active field in remote sensing applications. Although handling high detailed objects in Very High Resolution (VHR) optical image and VHR Digital Surface Model (DSM) is a challenging task, it can improve the accuracy of semantic labeling methods. In this paper, a semantic labeling method is proposed by fusion of optical and normalized DSM data. Spectral and spatial featur...

متن کاملGeographic Information Retrieval and Digital Libraries
In this demonstration we will examine the effectiveness of Geographic Information Retrieval (GIR) methods in digital library interfaces. We will show how various types of information may benefit from explicit geographic search, and where text-based place name search may be sufficient. We will also show how implicit geographic search (or geographic browsing) can be used to dynamically generate g...
متن کاملValidation of Volunteered Geographic Information Landuse Change Using Satellite Imagery
Land use change monitoring is one of the main concerns of managers and urban planners due to human activities and unbalanced physical development in urban areas. In this paper, a combination of remote sensing data and volunteered geographic information was used to assess the quality of volunteered geographic information on land use and land cover changes monitoring. For this purpose, the ORBVIE...
