Digital mapping, also known as digital cartography, is the method of making maps on a digital platform. Maps are a representation of a given area and are mostly dependent on symbols to represent the objects within the area. Most of the information that digital maps are made of is a culmination of satellite imagery and street level information. Therefore, Geographical Information Systems (GIS) are an integral tool for digital cartography.
Why use Digital cartography?
Maps are created by utilizing symbol to represent specific features of a given area, This means it is easier to make changes in case anything changes they are more up-to-date and can be remotely updated at a much lower cost, and labour.
- Digital cartography makes it easy to give a representation of a specific area in order to get a better perspective of the real world environment using software and would be less prone to human errors.
- They’re scalable – we can freely zoom them in and out and are more accurate.
- They are interactive (answer to the selected user actions – eg. Click)
The established concerns of digital cartography include the subfields of visual mapping, concerned with generation of graphic models of reality, and digital mapping, the technology concerned with the creation, management and performance of large integrated spatial databases. There is an increasing need within digital cartography to integrate data from different sources in both vector and raster formats.
With our services we offer creation of digital maps and layouts as per business requirements as Digital cartography is the new era of creating maps.
A map would display accurate information once it is registered with correct real-world coordinates. The images of the Earth’s surface taken with a satellite or an aircraft are ordinary digital photos that lack the information on how the areas on the photo correspond to the locations on the Earth’s surface. Without location information, these raster images cannot be used for analyses or comparisons with other spatial data
Georeferencing is the process of assigning real-world coordinates to each pixel of the raster ,map or aerial photo image. Georeferencing is crucial to making aerial and satellite imagery, usually raster images, useful for mapping as it explains how other data, such as the above GPS points, relate to the imagery. Georeferencing is a necessary step prior to the processing of spatial data
Very essential information may be contained in data or images that were produced at a different point of time. It may be desired either to combine or compare this data with that currently available. The latter can be used to analyse the changes in the features under study over a period of time.
With our services we intend offer accurate georeferencing as per your requisite.
Maps/data are always an important form of information, whether ancient, modern or future has been one of the most important achievements for humankind as it was because of this humankind was able to spread throughout the globe. Even before the modern computer technology was applied, maps/ data were created by manual operations. With the development of technology, people’s requirements for maps have been further improved.
With the GIS tool, the paper map can be converted into an electronic map that can be displayed on the screen through a series of processing, which can meet the new requirements.
We aim in converting digital image into a form usable in the GIS environment i.e. in a form such that each feature on the map has a geographic co-ordinate associated with it by using the method of heads-up digitizing. This method involves scanning a map or image into a computer and then tracing the points, lines and polygons using digitizing software.
Digitized maps/Data would be generated using GIS software that our experts have hands on experience and therefore promising accuracy high precision and quality products.
DATA MANAGEMENT AND SORTING:
GIS is a framework for gathering, managing, and analysing data.
There are two components to GIS data: spatial information (coordinate and projection information for spatial features) and attribute data. Attribute data is information appended in tabular format to spatial features. The spatial data is the where and attribute data can contain information about the what, where, and why. Attribute data provides characteristics about spatial data.
In the world of GIS, data plays a very important role and so does data quantity, which refers to credibility and accuracy of the data or more generally how good the data is. To maintain this data quality, we would provide Data management and sorting services would include reordering records with spatial and/or non spatial data like feature class, shapefiles or table, excel spreadsheets based on data requirements using tools that would enhance, develop, manage, and maintain data.
