New Datasets This Week: Geospatial Records, Hydrographic Surveys, and Public Health Data

What's New on Katzilla — Week of April 23, 2026

This week's batch of freshly indexed datasets brings a rich mix of geospatial boundaries, historical survey records, and social-services data. Here's a breakdown of everything that landed in the catalog.

Geospatial & Address Data (U.S. Census TIGER/Line)

Three new TIGER/Line shapefiles are now queryable through Katzilla:

• Owen County, KY (2016) — Address Range-Feature County-based file, useful for geocoding and routing workflows in rural Kentucky.
• Pembina County, ND (2016) — Address Ranges County-based Relationship File, ideal for cross-referencing street-level address ranges against administrative boundaries in the Northern Plains.
• Barron County, WI (Current) — All Lines file in XML, covering roads, hydrography, and rail lines for one of Wisconsin's fastest-growing rural counties.

Combined with Katzilla's existing TIGER catalog, these files let agents build precise, county-level address and routing contexts without touching raw shapefiles directly.

Historical Aerial & Hydrographic Records

For researchers and geospatial historians, this week adds some genuinely rare primary-source material:

• Jefferson County KY Aerial Photo Index (1993, Scale 660) — A Louisville Metro Government CSV cataloging aerial photography from over three decades ago. Perfect for land-use change analysis.
• NOS Hydrographic Survey H01152B (1872-03-12) — One of NOAA's oldest digitized coastal surveys, now accessible as structured XML.
• NOS Hydrographic Survey L02107 (1948-12-31) — Mid-20th-century seafloor soundings from NOAA's Department of Commerce archive.
• NOS Hydrographic Survey L01153 — An additional undated NOAA survey rounding out the hydrographic collection.

These records unlock temporal coastal and topographic comparisons that were previously locked behind agency portals.

Public Health & Social Services

• Connecticut School Readiness 2018-19 By Town (Feb) — Town-level early childhood education readiness metrics from the State of Connecticut.
• Connecticut Prescription Monitoring Program — Opioid and non-opioid prescription data, a critical dataset for public health and policy AI applications.
• Avenue NYC CFY17–CFY19 — New York City fiscal year data covering the Avenue NYC commercial revitalization program, useful for economic development analysis.

Query These Datasets Right Now

All ten datasets are live and accessible via the Katzilla unified API. Here's a quick example using the Katzilla Python SDK to pull the Connecticut Prescription Monitoring dataset:

from katzilla import KatzillaClient

client = KatzillaClient(api_key="YOUR_API_KEY")

result = client.datasets.query(
    dataset_id="ct-prescription-monitoring-opioid",
    filters={"year": 2019},
    limit=100
)

for record in result.data:
    print(record["drug_name"], record["prescription_count"], record["town"])

Swap in any of the new dataset IDs from the Katzilla catalog to explore the full set.
