Best GIS app in App Store

I've looked at every app in the App Store surrounding mapping and this is easily the best - outside of the ridiculously priced $300 apps which I didn't try. Highly recommended to anyone who wants offline shapefiles on their device. Two features I wish it had though are the ability to connect to WMS and to be able to click any line to get features without having to change the viewing layer that's active. Great work, hope it continues to be developed!

Best GIS on iOS

For my needs, this is the best GIS / GPS app for iOS. You can quickly and easily load, view, and edit shapefiles in a streamlined interface without a bunch of hassle. For more complicated field data collection and editing, you might want ArcPad, but if you want to do something straightforward like locate yourself in relationship to GIS layers and add record features, iGIS is dramatically more enjoyable to use and has a fraction of the learning curve. Oh, and you can have layers with different coordinate systems!

Awesome

This app is great if you are familiar with GIS. I work for a water utility and after loading in our shape files, this works like a dream.

Cool but misleading in some respects

I have been trying to find an easy-to-use GIS app to incorporate shapefiles and raster data into my daily fieldwork. I was excited to find this one, and it does have its perks. There are tons of choices for projections and the interface is pretty intuitive (with some major exceptions). There are quite a few inconveniences and drawbacks, however.

- To import raster data you have to have processed it using MapTiler, an open source software program that is only free if your images are smaller than a certain size (we are talking like 30 MB or less here) which is just not feasible for someone doing actual GIS work.
- All of the raster and shapefiles must be zipped and hosted on Dropbox (which is cool and convenient if you have enough space) - you can also use a USB.
- There is no intuitive way to add the imported layers to your project, and there does not appear to be a help file for the latest release, so this is somewhat frustrating (and as I write this I still have not figured out how to add my imported shapefiles).
- Would be nice if it displayed your location or coordinates anywhere in the free version since there are free apps that also do this.

Chump

All your files must be zipped to add. I don't have stuff zipped. What a pain. I like to add files from here and there. Looks cool though, probably won't use it.

FAQ

What is iGIS?

iGIS is a mobile GIS application for iOS that provides true GIS functionality on your iPhone. It allows users to load, view, investigate, create, and export their own spatial data over map service imagery. The app is designed for professionals and offers features like offline data access and support for various data formats.

What kind of data can I import and export?

You can import raster data (with pre-processing) and ESRI Shapefiles (.shp). The app also supports the export of your layers to ESRI Shapefiles, making it easy to use your data back in enterprise systems. It supports multiple layers of points, lines, and polygons, all stylable as you prefer.

Is iGIS free to use?

The application is free to download and use, but it operates on a freemium model. This means that while core functionality is available, certain advanced features or capabilities may require in-app purchases to unlock. Specific details on what is included in the free version versus paid features are typically found within the app's store listing or settings.

Can I use iGIS without an internet connection?

Yes, a key advantage of iGIS is that your spatial data is stored directly on your iPhone. This means you can access and work with your maps and data even when you don't have an internet connection, which is particularly useful for fieldwork in remote areas.

Who is the target audience for iGIS?

This application is designed for GIS professionals and individuals who have a foundational understanding of GIS concepts such as layers, shapefiles, and projections. It aims to provide powerful GIS tools in a mobile format for those who need to manage and analyze spatial data on the go.
