Frequently Asked Questions

If you didn’t find the answer to your question here please let us know.

General

Q: What am I buying?
A: By placing an order you get an access to data.nextgis.com service which generates easy-to-use spatial datasets. As a result you receive an archive with geodata in a selected format. The download link for this dataset is sent to you after the dataset if generated, to the email you indicated.

Q: Why do I need it? I can download OpenStreetMap data myself.
A: Our service saves the time you’d have to spend on data extraction and conversion. The advantages of the datasets generated at data.nextgis.com are described here.

Data Samples

Q: Where can I see the samples of the resulting datasets?
A: You can download samples of the resulting datasets in different formats from  “About”.

Q: Can I see a sample of a dataset for a specific country/region/city?
A: Unfortunately we don’t provide data samples for custom areas. Data samples available at “About” page fully reflect data structure, composition and styles which you will receive after placing your order.

Multiple Languages and Transcriptions

Q: Will the ordered dataset contain names of objects and points of interest in English?
A: Yes, it will.

Q: Will ALL objects in the dataset have English names?
A: We can not guarantee that the original data is complete, up-to-date or accurate.

Warranties and Limitation of Liability

Q: Is information from your database officially verified?
A: At data.nextgis.com you can order spatial datasets generated from different sources. We try to ensure that our datasets contain all data available at the original source. But we can not guarantee that the original data itself is complete, up-to-date or accurate.

Q: I bought a dataset from you, now can you explain to me how to work with it using my software?
A: We try to keep our prices as affordable as possible, and they don’t include the cost of our consulting services on how to use the data. We presume that you understand what you are buying, and we recommend to download and work with data samples prior to purchasing a dataset. If you need additional consultating or tutorial, we can provide them additionally плату.

Q: Will the resulting dataset contain the objects I need?
A: Yes, it will, but only if the original database from which the data is extracted contains them.

Q: Can you check beforehand if the resulting dataset would contain the objects I need?
A: Unfortunately, no. To check if a specific object exists or not is a manual procedure which significantly increases the cost of the order processing. You can check it yourself by accessing the original database at osm.org

Q: How long will the download link for my order work?
A: We keep the resulting datasets for 6 months after the order is fulfilled.

Ordering Data

Q: When will I receive my order?
A: Our orders are processed on average within 60 minutes. The processing time may increase due to the large volume of the ordered dataset.

Q: Are data updates included in my order?
A: When you order a dataset, we prepare it for you only once. If you want to receive regular updates for the data you order, please contact us.

Q: Can I order the whole country?
A: Yes, you can order data for any country in the world.

Q: When I purchase data for a country, does it include separate datasets for each country region or is it a single dataset for the whole country?
A: If you purchase data for a country, you receive a single dataset with all layers generated for the whole country. Separate datasets for each subdivision are not included.

Q: I want to order data for a few regions and I don’t want to place a separate order for each of them. Can I purchase them all at once?
A: Yes, please write to us, we’ll issue an invoice for all the data you need and will prepare all datasets from your list.

Q: I want to have a dataset compiled from a number of regions or representing a complex area. Can you do that?
A: Yes, please write to us, we’ll issue an invoice for all the data you need and will prepare a compiled dataset.

Q: I want to receive regular updates for my dataset, is it possible?
A: Yes, you can either purchase a dataset for a full price when you require an update or you can subscribe to regular updates. A discount for a package consisting of 4-10 updates is 25% from a full price (standard dataset price * number of orders), for a package consisting of 11-50 updates - it’s 35% from a full price.

Q: I want to receive a dataset for my city (county, town, village, etc.) but they are not in the list. How can I place an order?
A: Visit Custom area too and enter the name of your city, county or region in a search box. Select your region from the list of results. If the boundary is ok, you can proceed with an order. If you can’t find it - let us know.

Q: I paid for a dataset in one format, can I receive the same dataset in a different format?
A: Unfortunately, our service isn’t able to do this. 1 order means 1 data extract in 1 format. If you need the same data in a different format you’ll have to place a new order.

Data parameters

Q: What’s the scale of your maps?
A: Our service provides data from OpenStreetMap (OSM). OSM is created by thousands of iindividuals using different data source: satellite images, tracks, open data. There is no single scale that you can assign to the result. However, as you get vector data, you can use it at any scale you like.

Q: What’s the coordinate system of the data?
A: Data is in lat/lon WGS84 (EPSG: 4326). For ready-made GIS projects we use Mercator (EPSG: 3857).

Q: Can you reproject the result to another coordinate system?
A: Yes we can output data in other CRS. We charge additional 10 USD for this service per dataset.

Q: Can you add more attributes?
A: Yes, we can add more attributes. We charge additional 30 USD for this service. New data attributes will appear in the data structure and will be available afterwards.

Q: How actual is the data?
A: There is no single date. Each layer is made of features and each feature is created by OpenStreetMap editor at some day. We update syncronize with OpenStreetMap daily. So if your object was created yesterday it will become available through our service today.

Q: Can I have data for a different day?
A: Yes, we can provide data starting September, 2012. We charge additional 20 USD for this service per dataset. Let us know by email which date you need. Note that we don’t guarantee the completeness.

What can I do with the data

Q: Can I edit resulting data?
A: Yes. The resulting data is editable.

Troubleshooting

Q: I received a link to download data. But I can’t download them, indicating the email address to which the order was placed. The system reports that the user does not exist. What to do?
A: You need an account to download results, but we don't create accounts automatically. To download the result, you need:

  1. Go to my.nextgis.com
  2. Sign up (this needs to be done just once, account will work for future orders too)
  3. Click the download link again

Q: Some features are missing in the result I received. Is it a bug?
A: Not necessarily. Our service extracts data from OpenStreetMap and features you miss might be missing from the source database. You can make sure of that by looking at osm.org. If the feature is missing here — there is nothing we can do. If the feature is present in the source but missing in our results - let us know.

Q: Feature X in layer Y is shown incorrectly. Is it a bug? Can you fix that?
A: As a rule, we can’t fix errors in source data if they are unrelated to the conversion process. Additionally:

  1. You can fix the feature yourself at osm.org and order an extract again
  2. You can fix the feature yourself in the resulting dataset using your GIS (For example, if the format is ESRI Shape or GeoJSON - you can use NextGIS QGIS)

Q: Layer X is missing some attributes, is this a bug?
A: No. We don’t output all possible attributes as there are unlimited number of them. You can see the list of layers and attributes here. Click details after the attribute to see its description and possible additional attributes.

Q: I’ve ordered data two years ago. The link you’ve sent me no longer works. What should I do?
A: We keep the resulting datasets for 6 months after the order is fulfilled. You need to make your order again.
