When you create a new map, the **Add Data to Map** window appears.

To reopen the **Add Data to Map** window during your Studio session, click the **\+ Add Data** button.

The Add Data modal.

When data is added to the map, by default Studio attempts to [automatically recognize and create new layers](https://docs.foursquare.com/analytics-products/docs/data-import#auto-create-layers).

## Import Tabular Datasets

Tabular datasets (or datasets) contain rows and columns serving as the primary source for data analysis in Studio.

To import new datasets, follow these steps:

1. In the **Add Data to Map** window, navigate to the **Upload** tab.
2. Click **Browse**, drag and drop, or enter a valid URL to import your datasets.
3. Click **Add Data** to complete the import.

All uploaded datasets will appear in [the Data tab](https://docs.foursquare.com/analytics-products/docs/dashboard#data-tab) on the dashboard, where you can manage your datasets.

## Import Tiled Datasets

Tiled datasets (or tilesets) contain image files that represent real-world phenomena on your map. Studio can display:

- **Raster tiles**, which contain pixel-based imagery stored in a grid structure.
- **Vector tiles**, which contain vector-based imagery such as points, lines, and polygons.

Adding a new tileset to Studio.

Studio allows you to work with tiled datasets from several formats, including Vector tiles, Cloud Optimized GeoTIFFs (COG), and other [supported data formats](https://docs.foursquare.com/analytics-products/docs/data-formats).

To import new tiled datasets, follow these steps:

1. In the **Add Data to Map** window, navigate to the **Tilesets** tab.
2. Select your tiled dataset's type by clicking **Vector Tile** or **Raster Tile**.
3. Enter a name for your tileset, or leave the field blank to automatically name it.
4. Enter a URL pointing to your tileset.
5. Click **Add Data** to complete the import.

## Auto Create Layers

Studio will automatically detect layers, searching for column names in your CSV file that follow standard naming conventions. This operation is enabled by default, but can be disabled by unchecking the **Auto create layers** checkbox at the bottom of the modal.

Auto create layers detects several types of data, most of which relating to established spatial identifiers, such as:

- `lat` and `lng` points, which automatically create a [Point layer](https://docs.foursquare.com/analytics-products/docs/layer-point)
- `_geojson` columns which automatically generate a [Polygon layer](https://docs.foursquare.com/analytics-products/docs/layer-polygon)
- Well-known US administrative boundaries (such as ZIP codes or census tracts), created via [Shapify](https://docs.foursquare.com/analytics-products/docs/data-shapify)

> 📝
> ### Note:
> Studio recognizes a variety of column names and data types. For instance, `lng`, `long`, `lon`, and `longitude` will all be detected as a longitude column. If your data is not being automatically recognized, ensure your columns are named appropriately!
