Making Flood Marks Map

Making Flood Marks Map: Process

1 Making Flood Marks Map

Whole process of making Flood Marks Map

2-1

Flooding occurrence

• Cadastral map • Prevention equipment • Continual cadastral map

Pre-su rvey

• Weather information • Media, websites • Pictures of damaged area

Request data

Preparation of the f ield survey

Control point Surveying(GPS)

True elevation surveying

• With Total Station • Ruler, RTK

Present condit ion surveying

• Dataset from FMS • Sett ing the TOSS

• Manholes, f lood gates • Roads, houses, etc

Making the map

• Flood marks line • Making a map by TOSS

Making parcel report

• Importing CSV file • Made by EXCEL

Flood Marks Management System

Height surveying

Making Flood Marks Map: Process

1 Making Flood Marks Map Phase Ⅰ Research

2-1

Some can be downloaded through Flood Marks Management system - Cadastral map: It contains map and attribute data - Continual cadastral map: Flood marks map is made on this map, but it doesn’t contain attribute data Other can be requested to directly other institute - Zonal line, prevention equipment, TIN, etc

Request basic data

• Request data

• pre-survey

Direct research: f ield survey - When surveyor goes out to survey the area, it can be conducted w ith direct research - Take a picture of damaged area - Interview Indirect research - Weather information - Media - NIDP: prevention equipment

Pre-survey

Preparation of the mapping - Arrange the continual map

Phase Ⅱ Surveying

Control point surveying(GPS) True elevation surveying

Present condition surveying

it’s not essentia l

Inundated buildings, roads and fie ld

Manholes, flood gates and rainspouts to prevent flood

Present condition w ould be show n on the m ap w ith flood m arks line

Height surveying

It is the height from land to flood m arks

It has 7 levels having an in terval per every 50cm

There are 2 kinds of surveying:

- Range of the equivalent height survey

- Height of flood m arks : 3-4 points w ith in sam e range

GPS surveying should be preceded

True e levation of control point should be obtained before conducting flood m arks surveying

It is the height from m ean sea level to flood True e levation of flood: HB = HA + h A – h B

h B = S x sinα

Making Flood Marks Map: Process

Prepare basic map

Make true elevation of flood marks line

Register research point

Make height of flood marks line

Make flood marks map

Make a parcel report

Up-load to flood marks management system

Flood Marks Management System: Merits

2 Strong points of FMS

FMS

Increasing work eff iciency Web GIS +

The feature of Flood Marks Management system is work eff iciency and web GIS function

Capable of processing works simultaneously

- Request designing f lood marks map

- Download the products in real-t ime

- Ask the information by parcels, districts,

years

Accumulate the information continuously

- It has had data from 2006 to 2011

- Keep data almost permanently

- Capable of comparison research

Map screen tool

- Distance calculation

- Area calculation

- Coordinate calculation

- Map capture and printing

Show w ith the map and disaster prevention facilit ies

- Public off ice, refuge

- Water gate, levee, f lood pumping station

- By regional and by the name of facilit ies

Expected Effect

Expected Effects : Application

1 Expected application by KCSC

4-1

Obligate local governments to make f lood marks map NEMA is ready to make a rule to do it

Obligation Charge Hazard map

Smart phone App

Making app for smart phone related w ith hazard map It w ill be offered to every people w ithout cost

Previously the charge was cheaper than other surveys But this is almost same as others’ charge in 2012

KCSC is responsible for making f lood marks map KCSC is discussing duty of managing all kinds of hazard map

Upcoming application of Flood Marks Project

Expected Effects: Role

2 Role in National Disaster Management System and Integrated GIS

KCSC w ill be the main hub of managing Integrated GIS w ith experience of making FMS
