What's New in Nod

1.6.3

September 28, 2021

Minor compatibility update. The main highlights are: + Fixes and issue where sometimes points would be hidden from view unless scrolling + Fixes an issue where a polygon with 2 points would report its length as 0. This behaviour has been changed so that a polygon with 2 points is treated as if a line string for the purposes of determining length.

Good, but strange :)

It took me a while to get to understand how this app worked - the info isn’t great, but I have eventually worked it out and really like it. I do wish the points were bigger, though. When they don’t have the focus they can be really difficult to see. I only use points and never areas (polygons), so this is important to me.
When using ‘fit to layers’ it uses the screen as the area, but a lot of the area is under the control panel at the bottom, so that part of the layer - and, therefore, features - are hidden, which is a pain in the neck.
Lastly, and I find this bizarre, periods cannot be used in feature titles. I like to store the lat lons in there, too, and have to change the periods to full colons. I can’t see any reason for that. The same for other characters like uppercases, emojis and the like, which are good visual indicators.

Plotting Land

We wanted to work out the area for the plot of land we are planning on purchasing.
We were able to lock in points remotely and have the answer to our question while sitting in our sofa, no muddy feet this time!
This app does so many functions and I’m sure we will be using this again.

FAQ

What is Nod?

Nod is a mobile application designed to help users plot outdoor spaces and display them on a map. It allows for recording real-life locations, drawing geographic data, and performing measurements.

Who is Nod for?

Nod is intended for anyone who needs to record real-life locations on a map or compare them back to reality. This includes professionals like farmers, builders, scientists, and archaeologists, as well as map enthusiasts.

What formats can Nod export data in?

Nod supports exporting data in several common formats, including GeoJSON, CSV, HTML, and COLLADA (DAE). COLLADA files are particularly useful for generating data for 3D modeling applications.

How does Nod ensure data accuracy?

Nod offers high accuracy for adjusting individual points in features using its 'draw' mode, which includes a 'loupe' for magnified map interaction. It also allows for combining features and applying geometric operations for complex data creation.

Does Nod have ads?

No, Nod does not contain advertisements. It is a free application that is ad-free, allowing for an uninterrupted user experience.

What devices is Nod compatible with?

Nod is optimized for touch screen devices and is compatible with iPhone, iPad, and iPod. It requires iOS and is suitable for users aged 4 and above.

How does Nod handle data integrity?

Nod's proprietary file format (.nod) stores a complete hashed history of actions taken to create the data. This provides a full undo history and confidence that the data is as the original creator intended, offering a tamper-evident record.

How does Nod manage GPS usage for power conservation?

Nod conserves power by using the device's GPS system only when the app is in use and by manually operating the GPS. Users can also control the desired GPS accuracy to further reduce power consumption.
