Geospatial technology is a nerdy word for ‘location based technology’. If you’ve ever used an app to track your taxi or looked up directions to your nearest bar, you’ve used geospatial technology. GPS, satellites, and interactive maps are all geospatial technologies, and the information recorded from and released by them is called geospatial data. Another geospatial technology is a GIS, which is where tools like Mappt come in.
What is GIS?
GIS stands for Geographic Information System. This is a tool or software (e.g. Mappt) that allows you to create, edit, store, manipulate and export geospatial (location based) data. This data is plotted onto a map or satellite imagery of an area for the user to then analyse and form patterns, relationships and conclusions.
Who uses GIS?
More people than you think! Organisations both big and small use GIS on a daily basis. Industries include: environmental, mining, transport, Military, Forestry, Agriculture, Local and National Government, utilities and wildlife organisations. This can be to outline their crop fields, take geotagged photos of fallen trees, or show where a new road is going to run.
What is the future of GIS?
As the world evolves, an array of challenges come with it like urbanisation, climate change and pollution. From government and transportation, to environmental and healthcare, GIS is helping industries collect, analyse and discover fascinating findings from data. As more people understand GIS and the benefits of mapping data, we can expect GIS to infiltrate every industry, change the way we think and to become an essential part of decision making; just like it already is for geologists, mining companies and the military.
Yes. Mappt allows you to import, view, edit and export attribute data from all supported formats. You can also define constraints on attributes, such as defining valid ranges on numeric data; you can specify whether an attribute is optional during data capture; and finally, you can even define a list of dropdown values for an attribute.
Does Mappt support drop down or picklists in attributes?
Mappt allows the user to choose a value from a drop-down or “picklist” element. This saves time during data entry, and ultimately improves data capture accuracy!
Does Mappt support georeferenced/geotagged photos?
Mappt allows you to capture photos as points on the map, retaining their geographic location. You can also define any number of attributes to go with each photo, making it an excellent tool for surveys or inspections.
You can even edit and annotate the photos to highlight the specific areas of interest!
Does Mappt work offline?
Sure does! Mappt has advanced offline caching allowing you to work in areas where WiFi or 4G connections are obsolete.
Can I import my own satellite or aerial imagery into Mappt?
Yep. You can import ECW, JP2, or ESRI Compact Cache Bundles.
Does Mappt support geofences?
Yes! Using Mappt, you can turn any polygon into a geofence.
With geofencing enabled, Geofencing Alerts will fire if you venture into an Exclusion Zone; this is an effective way to define a “no-go” or “red zone” for your team.
Alternatively, you can define an Inclusion Zone (“green zone”) that will fire alerts if you step outside the zone.
Geofencing is an excellent way to help keep your team safe!
Does Mappt support DXF files (the format used by AutoCAD)?
No, but we have had some interest in this format and are keeping tabs on its demand. There are no plans at this stage to implement support for DXF.
How do I import a file from the SD Card into Mappt?
Connect your device to your desktop computer with the provided USB cable and follow the on screen prompts. Open the device with Windows explorer and then drag and drop to the file to the desired folder on the device. To import the file into Mappt click the Open Menu icon and select ‘Load dataset from Filesystem’.
How do I import a file from the internet into Mappt?
Locate the internet address of the file and click the Open Menu icon. Click ‘Load dataset from HTTP’ and enter the address. It is possible to copy and paste the address from the tablet’s browser.
Can I import a file from Google Drive into Mappt?
Yes. Click the load layer icon and select ‘Load from Google drive’. You will be able to connect to your Google drive account that your tablet is logged into.
How do I import a WMS layer into Mappt?
Click the load layer icon, then select ‘Load WFS/WMS’, and finally select ‘Load WMS’. The WMS dialog should appear, enter the server address into the text field and tap Load WMS. Once loaded it will provide you with a list of layers to choose from, select your desired layer(s) and tap ‘Load WMS’ again and Mappt will begin loading them!
How do I find my current GPS location in Mappt?
Activate your GPS by clicking on the satellite icon located in the top right. When the icon is blue your GPS is activate and two new icons will appear on the right. The cross-hair icon will jump to your current position and the data window on the bottom right will tell you the GPS coordinates.
How do I export data from Mappt and onto my PC?
Exporting files is only available to licensed copies of Mappt.
With a licensed version click the button to export a layer. You can select to export as a KML or a Shapefile. Select the location, click ‘New’ and enter the file name. It is a good idea to save the file to the external SD card so it can easily be retrieved through Windows explorer.
Why do my complex polygons change shape?
Spatial data can often take thousands of polygons which tax the devices ability to display the information. To ensure Mappt responds in a timely fashion, we have optimised the rendering of complex polygons. See our blog for further details.
Can I link in an external GPS?
Yes. Check out our guide on the blog on how to link in an external GPS to improve accuracy for over the inbuilt tablet GPS functionality.
Is Mappt available on iOS?
We have a version of Mappt available for iPhone and iPad called Mappt Elements. Mappt Elements is free to download and you can purchase the features you need in-app. It’s not as advanced as Mappt for Android, but it’s getting there! To find out more, please head to the Mappt Elements website.
