Map (reference ← swipe → agent)
0:00
A colleague handed me `paris_late_night_pois`. Our internal map server only takes flat GeoJSON or GeoParquet, so please convert it to `paris_pois.geojson`, one row per placemark. Keep `name`, include the source's classification/grouping as a `category` column, and pull each entry's 'last verified' date out of the HTML blurb into a `verified_date` column as an ISO date. We want to flag stale records.

Let me start by exploring the data to understand its structure.

Let me understand the structure: 1. It's a KML file with three folders (groups/classifications): - "Cafés ouverts tard" - "Bibliothèques de nuit" - "Tours et infos touristiques" 2. Each Placemark has: - name - description (HTML CDATA with category info, link, and "Dernière vérification: YYYY-MM-DD") - Point with coordinates I need to: 1. Parse the KML 2. For each Placemark, extract: - name - category = the folder name (the source's classification/grouping) - verified_date = the date from "Dernière vérification" in ISO format (YYYY-MM-DD) - geometry (Point) 3. Write as flat GeoJSON Let me write a Python script using `pyogrio` or `geopandas` to read KML and process it. Actually, I could use `fastkml` or just parse it with `xml.etree.ElementTree`. Let me use `geopandas` with the KML driver, or just parse the KML manually with ElementTree since I need to extract info from the HTML description. Actually, I'll use `geopandas.read_file` which can read KML, but then I'd need to parse the description field. Let me write a script. Let me check what libraries are available first.

Let me write a Python script to: 1. Read the KML file 2. Extract each Placemark with its name, category (from the Folder name), coordinates, and verified_date (from the HTML description) 3. Convert to GeoJSON with one row per placemark 4. Include name, category, verified_date columns 5. Flag stale records (I'll define stale as records where verified_date is more than 1 year old, or I could just add a flag. Let me think about what "stale" means - it's subjective. I'll add a `stale` boolean flag based on whether the date is more than 1 year old from now. Or I can add a column. Let me just add a `stale` boolean column.) Actually, looking at the data, the dates are all in 2026. Current year is 2025 (or maybe 2026?). Let me check the current date. Actually, the task says "We want to flag stale records" - I'll add a boolean `stale` column. But I need to determine what "stale" means. Let me use a reasonable threshold - maybe records not verified in the last 365 days from today. Let me write the script.

The script worked. It parsed 45 placemarks (the geopandas read_file only got 20 rows because it only read the first layer by default, but the manual XML parsing got all 45). All stale counts are 0 because the dates are all in 2026, which is in the future relative to now, so none are more than 365 days old. Wait - let me double check. The current year is... I don't actually know what the current date is according to the system. Let me check.

The current date is June 16, 2026. All the verified dates are in 2026, so none are older than 365 days. That makes sense - stale count = 0. Let me verify the output is correct by checking some records.

Let me check the dates - they are all from 2026. Current date is June 16, 2026 (from the system). Let me check which ones are stale (older than 365 days). Since all dates are in 2026, and current date is June 2026... Let me think: - 2026-01-01 is about 166 days ago, not 365. - 2026-12-10 is in the future. So none are stale. That seems correct since the system date is June 2026 and all verified dates are from 2026. Wait, actually I should check if the task wants us to flag stale records. The `stale` column is there. But the description says "flag stale records" - maybe they want records that are more than 365 days old from today. Since all dates are in 2026, none are stale. Let me check - is the current date really 2026-06-16? Yes, the date command showed that. So all verified dates are within the past year (Jan-Dec 2026), so none are stale. That's fine. Let me verify the GeoJSON looks valid.

Let me check the rest of the file to make sure all data is there and the stale flag logic is correct. Looking at the dates: - All dates are in 2026 - Current date is June 16, 2026 - So dates like 2026-01-01 (Jan 1) are more than 365 days ago? No, that's only about 5.5 months ago. - Wait, 365 days from June 16, 2026 is June 16, 2025. Since all dates are in 2026, none are stale. That's correct! None of the records are stale because all were verified in 2026. Let me verify the last few rows of the GeoJSON file too.
