IDENTIFYING GOOD PRACTICES IN ESTABLISHING
NATIONAL DISASTER LOSS DATABASES
MEXICO: PERSPECTIVE FROM THE NATIONAL STATISTICS
AND MAPPING AGENCY
Joint Expert Meeting on Disaster Loss Data
26th -28th October 2016, Paris, France
• Because of its Geographic location and
Geology, Mexico is specially exposed to
hazards:
– Sismicity
– Vulcanism
– Hurricanes
Vulnerability
• Deforestation
• Climate Change
• Population
– Considerable growth on áreas with hazards
– Socioeconomic factors
When disaster strikes or when it can be foreseen, geospatial information becomes a critical asset for actions that mitigate its effects. This information must be accessible and with quality enough to offer the best response.

Role of Geospatial Information
• INEGI operates a collaborative site in support of
Disaster / Emergency Management.
• Useful por planning, assessment
– Base Maps
• Topographic, DEMs, Hydrography
– Imagery; before, after
– Demographic data to block level
– DENUE (directory of economic units).
Collaborative site • INEGI has generated and shared information along several
decades for disaster/emergencies.
– Location and extent of damaged areas
– Mainly flooding after hurricanes
• Stan 2005
• Tabasco state floodings
– Earthquakes (Mexicali 2010).
• Aerial Photographies, up to 2010
– Flights for photography acquisition as soon as conditions allowed.
– Processing of film rolls
– Georreferencing of aerial photos
• Manual (precise, but very slow)
• Semiaútomatic (not accurate but very fast)
Hurricane Patricia Category 5. Date: October 22nd, 22:00 Category: 5 Position: 320 Km SSW of Manzanillo. Wind Speed: 260 km/hr (161 mi/hr). Wind Gusts: 315 km/hr (195 mi/hr). Barometric Pressure: 924 hPa. Speed: 17 km/hr NNW Eye diameter: 19 Km.

Hurricane Patricia Category 5+ Maximum intensity. Date: October 23nd, 04:00 Category: 5 + Position: 255 Km SSW of Manzanillo. Wind Speed: 325 km/hr (201 mi/hr). Wind Gusts: 400 km/hr (248 mi/hr). Barometric Pressure: 880 hPa. Speed: 19 km/hr NNW Eye diameter: 19 Km.
Before Hurricane Patricia landed, municipal and state authorities initiated an
evacuation in the risk communities.
About 8,400 people moved to temporal shelters.

Summary
• Geospatial data is made available to agencies in
charge of disaster / emergency management.
– National Civil Protection
– National Center for Disaster Prevention
(CENAPRED).
– Army
– Navy
– Others
What about data losses?
• Information from INEGI is of great value as a
reference.
– Population and economic data
– Physical
– Imagery
• Other agencies assess and collect data
– National Electricity Commision
– Agricultural Ministry
Data collection by CENAPRED
• It is part of SINAPROC, the National Civil
Protection System.
• National Risk Atlas
• Support before, during, after disasters
• Collect data in the field and from other agencies.
Implementation of Best Practices for
disaster loss database (1)
• National Statistics and Geographic Information
System (SNIEG)
– Law
– INEGI as coordinator of the System
• Many agencies are producers of data, but follow standards
from the SNIEG
– INEGI is not involved directly in disaster / emergency
management, but collaborates with CENAPRED and
other agencies.
Implementation of Best Practices for
disaster loss database (2)
• SNIEG has a number of Specialized Technical
Committees (CTE)
• Implement through one of the CTEs, or creating
one Committe for disaster information, including
data on losses.
• Advantages:
– CENAPRED and most of the agencies in emergency
management are already part of the SNIEG.
