CsvLayers Tutorial: Plotting Geographic Coordinates CsvLayers is a lightweight, web-based mapping tool designed to transform flat CSV files into interactive geographic visualizations. This tutorial will guide you through the process of importing latitude and longitude data, styling your map layers, and exporting the final visualization. 1. Preparing Your CSV Data

Before uploading your data, you must format your CSV file correctly. The mapping engine requires explicit geographic coordinates to plot your points accurately.

Header Row: The first row must contain descriptive column names.

Coordinate Columns: Create separate columns explicitly named latitude and longitude (or lat and lon).

Decimal Degrees: Format your coordinates as decimal degrees (e.g., 40.7128, -74.0060), not as Degrees Minutes Seconds (DMS).

Clean Formatting: Remove any currency symbols, brackets, or text strings from your numeric coordinate fields. 2. Importing Data into CsvLayers

Once your data file is ready, you can load it into the application platform. Open the CsvLayers interface in your web browser. Click the Import Layer button on the left sidebar.

Drag and drop your .csv file into the designated upload zone.

Verify the column mapping in the preview window; ensure the system correctly identifies your latitude and longitude columns. Click Generate Layer to plot the points onto the base map. 3. Customizing the Map Visuals

After plotting your coordinates, you can customize the styling to make the geographic patterns easier to interpret.

Base Maps: Toggle between satellite imagery, terrain views, or minimal light/dark backgrounds depending on your data contrast needs.

Point Styling: Adjust marker sizes, transparency levels, and border widths to prevent overlapping in high-density areas.

Color Coding: Bind marker colors to specific data columns to create thematic maps (e.g., coloring points by category or revenue).

Pop-up Windows: Select which CSV data columns will display when a user clicks on a map marker. 4. Exporting Your Map

CsvLayers provides multiple methods for sharing your finalized geographic visualization.

Interactive HTML: Export the map as an independent HTML file that retains full zoom and pan functionality in any browser.

Static Image: Save the current view as a high-resolution PNG or JPEG file for presentations and print reports.

Shareable Link: Generate a hosted URL to share the interactive map directly with colleagues or clients.
