## What is SoilWeb?

The SoilWeb for iOS application accesses soil survey information (the SSURGO dataset, published by the USDA Natural Resources Conservation Service) at your current location. 

This app was designed to be a lightweight version of the SoilWeb GMap web application. SoilWeb GMap features an interactive map for viewing and querying individual map units, while this app does not. However, SoilWeb for iOS conveniently provides a link to the SoilWeb GMap web app.

SoilWeb GMap is available at https://casoilresource.lawr.ucdavis.edu/gmap/

More information about SSURGO is available at https://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/survey/geo/?cid=nrcs142p2_053627

Features of SoilWeb for iOS include:

- Soil profile sketches, estimated proportions, and geomorphic position of soil components associated with the SSURGO "map unit" identified at your current location.

- Map unit aggregate data such as estimated water holding capacity.

- Soil survey area scale and publication date.

- Component details: soil taxonomy, soil property depth profiles, land classification ratings, hydraulic and erosion ratings, forest productivity, soil suitability ratings.

- Links to Official Series Descriptions (OSDs) generated automatically.

- Component links to related web apps: Series Extent Explorer (SEE) and Soil Data Explorer (SDE).

- Link to the SoilWeb GMap web application at your current location.

- Location accuracy setting allows you to select between standard accuracy (less accurate, uses less battery power) and high accuracy (more accurate, but may use more battery power).

- Location auto-refresh feature allows you to continually look up soil data at a specified time interval.

### 5/5 — Nice work

*2023-07-16, version 2.3*

Incredible app! Go soil science. Future update should allow the “view map” feature as in the desktop version. This is essential to see nearby soil types rather than just those under your current location.

### 5/5 — Change Soil Series Font Color

*2023-06-08, version 2.3*

Have loved this app for years; so grateful to have it. Would like to see the soil series name in a font color other than white; very difficult to read outdoors.

### 3/5 — Gave soil for wrong area

*2022-02-11, version 2.3*

The map has the correct gps coordinates, however the software gave us a physical location and soil data for an area 4 miles east of the gps location. Needs work.

### 3/5 — Worked great until it didn’t

*2020-10-30, version 2.1*

I used this app daily for my work. Then suddenly one day it wouldn’t load then it wouldn’t even open. I deleted it. Downloaded it. Emailed the developer who didn’t know anything was wrong. So now for about 3 to 4 months it doesn’t work.

### 1/5 — Doesn’t Open

*2020-10-19, version 2.1*

Downloaded, wouldn’t open. Keeps crashing. Reading other comments seems like this has been happening for a while. Leads me to believe there’s no support.  I’ll stick with other resources.

### 5/5 — Help

*2020-10-13, version 2.1*

Will not open for some reason. I’ve had this problem for about 2 weeks. Anyone know why? This app is extremely helpful and would love to continue using it!

### 1/5 — I liked it when it worked but now it crashes immediately when opened

*2020-10-11, version 2.1*

I think the title says it all

### 1/5 — Doesn’t work on iOS 14

*2020-10-05, version 2.1*

Please update

### 3/5 — Nice when it works

*2020-10-03, version 2.1*

Currently crashing on opening, when it works it is a very nice little app that gives you soil data for where you are standing. The soilweb website is necessary if you want to look around thoug

### 1/5 — Crashes

*2020-09-18, version 2.1*

Not supported by iOS 14
